Acoustic Treatment

Professional quality acoustic treatment at affordable prices. Transform your rooms sound with our acoustic panels and diffusers.


A perfect sound starts at the source.

The JMH Sound Design vision is to provide everyone with solutions to achieving a professional sound. This vision has expanded to include room treatment solutions, ensuring all your audio needs are met.

Does your room...

Sound unbalanced?

Have excessive reverberation and delay problems?

Sound dull or lifeless?

If so, JMH Sound Design is developing a solution for you!

Room acoustics are often a neglected factor of the design process and furnishing of a room, particularly for home studios, theatres, and offices. Poor acoustics are always noticeable, and the solutions can be confusing. JMH Sound Design Acoustic Treatment solutions aim to address these problems. Professional room treatment can be marketed as a convoluted problem with advanced solutions. This is not the case. Treating a room can be quite simple, and follows a formula that our acoustic panels and diffusers abide by.

This is an exciting time for us as we look to expand the ways in which we can help you achieve audio perfection. Our acoustic treatment line of products are currently in development and we are proud to be able to offer our Standard and Bass Trap panels as a demo product in the near future.

Our Products

Standard Panel (DEMO)

1200mm X 470mm X 120mm (L, W, D)

* Product is limited to 1 colour and 1 depth variation in the demo stage due to a lack of different materials. We will be offering different colours and thicknesses for all panels in the future. Different colours and thicknesses are available at this stage but are still limited and order size requirements apply.

Bass Trap (DEMO)

1200mm X 470mm X 250mm (L, W, D)

* Product is limited to 1 colour and 1 depth variation in the demo stage due to a lack of different materials. We will be offering different colours and thicknesses for all panels in the future. Different colours and thicknesses are available at this stage but are still limited and order size requirements apply.

As the development process advances, more information on our products will be provided.

Understanding Sound

The quality of sound in the sense of sound reproduction in a room can be thought of as intelligibility; as in, is the sound clear? Take for instance the common church, or hall. These spaces are often large, and carry with them a similar sized reverberation time – this makes the sound in that space sound distant, and without clarity. This concept can also be applied to recording studios, or critical listening spaces – having a controlled room can help to ensure that any recorded sound, or played back sound is captured or listened to as intended.

Sound can behave in a number of ways in the common room. Sound will reflect off of the walls, ceiling, and floor of a room once the rooms capacity to dissipate sound has been breached. These reflections can be categorised as first order reflections, and second order reflections.

First order reflections are reflections that occur off of close reflective surfaces. The reflected sound from these surfaces returns to the listener in a manner that is out of phase with the original sound. This causes the issue of ‘comb filtering’, and generally obscures the intelligibility of certain frequencies. Treating first order reflections is of upmost importance and should be considered priority in your journey to treat your room.

Second order reflections are heard as the reverberation trail of a sound. This is particularly apparent in churches. Dealing with second order reflections is fairly simple, and can be achieved by placing adequate amounts of sound absorbing panels around your room or space. This can also work to control ‘flutter echo’ which is caused by reflective parallel surfaces. By placing absorbers across the parallel walls of your room, you will treat the flutter echo of your room as you are preventing the echo from sustaining.

Sound and Thermodynamics

Sound is energy, and is absorbed through the function of ‘thermodynamic transfer’, that is, turning energy into heat. For the purposes of porous absorption (which is the design philosophy of our Standard and Bass Trap Panel) this ‘thermodynamic transfer’ works through sound causing the small fibres of the insulation within the panel to vibrate. As the fibres are extremely thin, they absorb sound very efficiently as they move freely within the panel. Having a multitude of acoustic panels around your room will quickly tame any first order reflections as the rooms capacity to transfer sound energy into heat is increased.

Low frequency information is particularly difficult to absorb due to the length of low frequency wavelengths. Bass frequencies are powerful, they require large speakers to be produced accurately, and take large amounts of power to be generated. As such, in order to tame bass frequencies, you require a fairly dense, and fairly thick acoustic panel. This is why thin acoustic foam is useless at controlling bass frequencies, it is physically impossible. Using the philosophy of increasing panel thickness can only work to a certain extent when using only the philosophy of porous absorption, as if you wanted to target for instance 172hz (2m wavelength) using the principles of quarter wavelength absorption, you would need a panel that is 50cm thick!. This is simply impractical. In order to work around this issue, and ensure that we can offer a product that is effective in treating bass frequency issues whilst remaining practical, we have employed a hybrid system of absorption using porous absorption in combination with diaphragmic absorption.

Porous absorption as explained above works through placing porous material in areas of low air pressure and high particle velocity. For this method to affect bass frequencies due to their large wavelength, you need dense and extremely thick porous material. Diaphragmic absorption is the process of creating a ‘diaphragm’ or ‘membrane’ that sympathetically vibrates to the target frequency, in effect dampening that resonant frequency. Diaphragmic absorbers specifically target certain frequencies. What frequency you target depends on the mass of the diaphragm, and the amount of air behind the diaphragm (these diaphragms are attached to a sealed box). Within this air gap behind the diaphragm, you can place porous absorbers, which change the way the air reacts to pressure, essentially increasing the effectiveness of the diaphragm.
