How many Acoustic Panels do I need?
This depends on the size of your room and what you want to use it for.
For example, a small home studio room might benefit from a few carefully positioned panels, while a rehearsal room or office may need more extensive coverage to reduce echo throughout the space. For more demanding applications, bass traps can provide additional low-frequency control.
A certain amount of trial and error is usually needed to find the right balance. Below, we'll go through the main considerations, with practical examples to help you decide how much treatment you'll need and where to position it.

Live vs Dead Spaces
A room's acoustic characteristics, or the 'sound' of a room, can broadly be described as live or dead.
A room with lots of reflective surfaces will sound live, for example painted walls, wooden floors and bare windows. Sound reflects around the space, creating echo and reverberation.
A dead room is the opposite, with very little reverberation. Most of the sound is absorbed rather than bouncing repeatedly around the space.
Sometimes a live-sounding room can be desirable. For example, a large recording space with good natural acoustics can add character and ambience to a drum recording.
However, a lot of modern music production takes place in small, rectangular rooms such as bedroom studios, rehearsal rooms and project studios. These can produce unpleasant reflections and short, muddy-sounding reverberation.
We don't want to capture unwanted room sound in our microphones, and we don't want excessive reflections interfering with what we hear when mixing or listening. This is why we use acoustic treatment.
A completely dead room is not generally necessary or desirable. Whether you're recording, mixing, rehearsing or simply improving the acoustics of an office, the aim is to achieve a controlled, balanced sound without excessive reverberation.
Use Your Furniture
Studio equipment isn't usually the only thing in the room. Furniture and soft furnishings can also contribute to better acoustics.
If your floor is made of wood, concrete or another reflective material, consider putting down a rug or carpet. This can help reduce reflections from the floor.
Similarly, windows can be covered with thick curtains, while sofas and upholstered furniture can provide useful absorption.
Irregular surfaces, such as bookshelves filled with books, can also help scatter reflections around the room rather than reflecting them directly back.
These furnishings won't absorb all frequencies equally, particularly at the lower end of the spectrum, but they can still make a worthwhile difference.
A furnished bedroom may need considerably less acoustic treatment than an empty room of the same size.
Acoustic Treatment Zones
There are several distinct stages in which we perceive the sound coming from our monitors.
First is the direct sound, travelling straight from the speaker to our ears.
Next come the early reflections, where sound bounces off nearby surfaces such as walls, ceilings and desks before reaching our listening position.
Finally, we hear the effects of sound reflecting repeatedly around the room, contributing to its overall reverberation.
Understanding these different types of sound helps us decide where acoustic treatment will be most useful.
Direct Sound
The direct sound travels straight from your speakers to your listening position, without first bouncing off another surface.
For mixing and critical listening, we want to hear this sound as clearly as possible, without excessive interference from room reflections.
This helps us make more accurate judgements about tonal balance, clarity and stereo imaging.
Early Reflections
Shortly after the direct sound reaches your listening position, you'll hear reflected sound coming from nearby surfaces.
These early reflections typically come from the side walls, ceiling and desk, depending on the position of your speakers.
Treating these reflection points with acoustic panels can make a significant improvement to clarity and stereo imaging.
One simple way to identify the side-wall reflection points is the mirror trick.
Sit in your normal listening position and have someone move a mirror along the side wall. Wherever you can see one of your speakers in the mirror, you've found a reflection point.
Repeat this process on the opposite wall.
Placing acoustic panels at these positions helps reduce the reflected sound reaching your ears.
This is often one of the most effective ways to improve a mixing or listening position with a relatively small number of panels.
Back Walls
In most rectangular rooms, the back wall is parallel to the front wall. These parallel surfaces can contribute to flutter echo and unwanted reflections.
Acoustic panels on the back wall, behind your listening position, can help reduce these reflections.
If the room is particularly reflective, increasing the amount of treatment on this wall can also help reduce overall reverberation.
Low-frequency room resonances are a separate consideration, which we'll discuss in the Bass Traps section below.
Side Walls
Side walls are another important area, particularly where large, parallel surfaces allow reflections to bounce repeatedly around the room.
For mixing and critical listening, the first reflection points on the side walls are usually a priority.
Additional panels elsewhere on the side walls can help reduce flutter echo and general reverberation throughout the space.
Placement vs Coverage – What's Most Important?
This is an important distinction, and the best approach depends on what you're trying to achieve.
For mixing and critical listening, accurate placement is particularly important.
By treating the main reflection points around your speakers and listening position, you can achieve a noticeable improvement in clarity and stereo imaging with relatively few panels.
However, it's important to understand what this treatment is achieving. Installing 4–6 panels at carefully chosen reflection points might considerably improve the sound at your desk, but it won't necessarily make the rest of your room sound much less echoey.
For general echo and reverberation control, the overall amount of absorption becomes especially important.
In a rehearsal room, office, podcast studio or live recording space, there may not be a single listening position to focus on. Instead, the aim is often to reduce unwanted reverberation throughout the whole room.
In these situations, it's usually more useful to distribute acoustic panels across the walls, rather than concentrate all your treatment around one particular position.
The more absorption you introduce, the more you can generally reduce the room's overall reverberation.
How much coverage do I need?
A few panels can make a noticeable improvement, especially in a small, furnished room.
But if you're trying to make a very reflective room sound significantly more controlled, you may need a much greater amount of coverage.
For rooms requiring substantial reverberation control, covering around 40–60% of the available bare wall space is a useful rough guide.
This isn't a fixed requirement. The amount of treatment you need depends on the room's size, furnishings, existing acoustic characteristics and how much reverberation you're trying to remove. Many rooms will need considerably less.
It's also worth distributing your treatment around the space rather than covering just one small area of wall. Ceilings can be another useful area to treat, particularly in rooms with hard floors.
Our recommendation is to start with a sensible amount of treatment and listen to the results. If the sound at your listening position has improved but the room still feels too echoey, you may simply need more overall panel coverage.
Measure the Response in Your Room
We recommend taking a trial-and-error approach to room treatment. Start by assessing the natural sound of your room, experiment with panel placement, then listen or measure again to evaluate the improvement.
For general echo and reverberation problems, a simple clap test can be a useful starting point. Listen for flutter echo, ringing and excessive reverberation, and compare the results before and after installing your panels.
For more accurate measurements, particularly in mixing and listening rooms, specialist software can help you identify problems throughout the frequency range.
ClapIR – iOS
A convenient tool for estimating room reverberation using a mobile device.
Room Acoustic Meter – Android
An Android tool for basic acoustic measurements.
Room EQ Wizard (REW)
Free software for more detailed room acoustic measurements across the frequency range. Particularly useful for investigating low-frequency response and room resonances.
For accurate frequency-response measurements, we recommend using a suitable calibrated measurement microphone.
Example 1 – Small Listening Room
For an average small mixing or listening room, we recommend starting with around 4–6 acoustic panels, positioned to treat the main reflection points.
In this example, we've installed one panel to the left and one to the right of the listening position, and two on the wall behind.
This can make a noticeable improvement to clarity and stereo imaging without requiring a large amount of treatment. Additional panels can be used where necessary, for example to treat ceiling reflections.
Remember, though, that this is primarily about improving the sound at your listening position. Even 4–6 carefully placed panels won't necessarily remove echo from the entire room, particularly if it has large areas of bare wall.
If your goal is more general reverberation control, you may need additional panel coverage.
For serious mixing and critical listening, we also recommend considering bass traps as part of your overall treatment.

Example 2 – Small Listening Room / Further Treatment Required
Some rooms are more problematic than others, and you may still notice unwanted reflections or reverberation after treating the main reflection points.
In this situation, additional panels can help.
The wall behind your monitors is a useful area to consider, along with the ceiling above your listening position.
If the room still sounds generally echoey, try distributing additional panels across untreated wall areas to increase the overall amount of absorption.
Remember that improving your listening position and reducing reverberation throughout the room are related, but slightly different objectives. You may need to address both.

Example 3 – Larger / Problematic Mixing Room
In this example, the room is a little larger and has an awkward layout, with a window at one end and an L-shaped floor plan.
Some additional treatment and experimentation will probably be necessary to achieve a balanced sound.
Start by treating the main reflection points, then consider additional panels on the walls and ceiling to control reverberation across the room.
For a serious mixing room, we would also recommend incorporating bass traps. These complement the panels by providing additional low-frequency absorption, helping to control resonances that can affect the accuracy of your monitoring.
Speaker placement and listening position can also have a substantial effect on bass response, so it's worth experimenting with these as part of the setup.
There's no need to tackle everything at once. Start with the panels, assess the improvement, then add further treatment as required.

Example 4 – 'Live Room' for Recording
Here we have a room where a band records, with several microphones positioned around the space.
Unlike a dedicated mixing room, there isn't necessarily one fixed listening position. Instead, the aim is to reduce unwanted room reflections and reverberation across the whole space, so that microphones capture a cleaner, more controlled sound.
This is where overall panel coverage becomes particularly important.
Rather than concentrating only on individual reflection points, we recommend distributing panels around the walls to reduce reverberation throughout the room.
For a room where a heavily damped sound is desired, covering around 40–60% of the available bare wall area can be a useful guide.
The same approach works well for rehearsal rooms, larger podcast studios, offices and other spaces where general echo and reverberation are the main problems.
Of course, not every live room needs to be heavily damped. Some natural ambience can be desirable, particularly for certain instruments and recording techniques.
The amount of treatment should always reflect the sound you're trying to achieve.

Bass Traps – Do I Need Them?
AudioSilk acoustic panels are broadband absorbers, providing effective absorption across a wide range of frequencies.
They're particularly useful for controlling the reflections and reverberation that affect clarity, making them an excellent starting point for most room treatment projects.
However, troublesome low-frequency resonances can require more specialised treatment, particularly in smaller rooms. These resonances can cause certain bass notes to sound too loud, too quiet or to linger longer than they should.
This is where our dedicated bass traps come in.
AudioSilk bass traps provide additional low-frequency absorption, helping to reduce troublesome bass resonances and improve clarity and balance at the lower end of the frequency range.
Should I start with panels or bass traps?
For most rooms, we recommend starting with acoustic panels.
By reducing unwanted reflections across the mid and higher frequencies, panels can produce a substantial and immediately noticeable improvement to the sound of your space.
They're also a practical, affordable first step, allowing you to assess the results before deciding what additional treatment might be needed.
If your room still sounds too echoey, you may benefit from more panel coverage. If you're experiencing boomy or uneven bass, bass traps may be the more useful next step.
For music production, mixing and critical listening, however, bass control is an essential consideration. Accurate monitoring requires good control across the frequency range, and we generally recommend combining acoustic panels and bass traps.
There's no need to tackle everything at once. It's perfectly reasonable to start with panels and build up your treatment in stages, even when planning a more complete mixing room.
A Complete Acoustic Treatment System
AudioSilk acoustic panels and bass traps are designed to complement each other, providing effective sound absorption across a much broader frequency range than panels alone.
Our acoustic panels control unwanted reflections, echo and reverberation, while our bass traps provide additional absorption at lower frequencies.
Together, they form a complete acoustic treatment system for home studios, helping to create a clearer, more balanced and more accurate listening environment.
For podcasting, streaming, voice recording and general echo reduction, acoustic panels alone will often provide all the treatment you need.
For serious mixing and critical listening, combining panels with bass traps offers a more comprehensive approach.
Both products have been independently tested to the international ISO 354 standard. You can explore the results in our acoustic performance graphs, which show the sound absorption coefficients across different frequency bands.
Where should I place bass traps?
Bass traps are typically installed in room corners, where they can provide effective low-frequency absorption.
We recommend starting with the two front corners of your room, near your speakers. Listen to the results, or take acoustic measurements, to assess the improvement.
If further bass control is needed, add traps to the rear corners. Bass traps can also be stacked vertically to increase the amount of low-frequency absorption.
It's also worth experimenting with your speaker placement and listening position, as these can have a significant effect on low-frequency response.
Bass can be challenging to control, and even good treatment won't necessarily produce perfectly even bass throughout a room. However, combining appropriate bass trapping with sensible speaker positioning can make a worthwhile improvement.
AudioSilk bass traps are designed for easy corner installation, with both removable and permanent mounting options. See our installation guide for detailed instructions.
Where should I start?
For most rooms, start with acoustic panels to control unwanted reflections and improve clarity.
If your main goal is to reduce general echo and reverberation, focus on achieving enough panel coverage across the room.
If you're creating a mixing or critical listening space, prioritise your main reflection points, then incorporate bass traps for additional low-frequency control.
You can always build up your treatment gradually, assessing the improvement at each stage.
