If you want to improve the quality of your home theatre listening experience, there are many room acoustic solutions that you can try out. These will dramatically improve the overall acoustic quality of your space, making it easier to hear and understand conversations, listen to music, or watch movies.

Reverberation is a common problem in many rooms and can cause echoes, frequency build up and other issues that affect your listening experience.


Absorbers reduce reverberation in a room by taking in sound waves and trapping them, rather than reflecting them back into the space. They are usually installed behind or next to a wall to improve the room’s acoustic performance.

A porous material, such as mineral wool or acoustic foam, can absorb sound in various ways. The most important acoustical properties of porous materials of are their airflow resistivity and characteristic impedance.

The air flow resistance of the material determines how much energy it takes to penetrate through the pores and reflects off the surface. The higher the resistance, the less sound is able to penetrate and reflect.

Many acoustic absorbers come in a variety of shapes, such as egg cartons or diffusers. However, if the absorbent is too close to the wall it can actually decrease its acoustic performance of soundproof curtains.


Diffusers scatter sound energy, breaking undesired reflections and reducing the effect of resonant modes without affecting reverberation time. Diffusers are an essential part of any acoustic treatment scheme, complementing absorbent panels and bass traps.

The first step to optimizing your sound is to test the room’s acoustics. This is done by listening to the room at various times of the day and at different locations in the room.

In general, rooms with parallel walls and lots of glass and reflective surfaces have bad acoustics. They also tend to have a lot of standing wave distortion which is very distracting for audio reproduction.

Diffusion is a great way to make these rooms more aesthetically pleasing. Depending on your needs, you can choose diffusers that are unidirectional (quadratic), bidirectional or skyline.

Bass Traps

Bass traps are acoustic absorbers designed to optimize the sound in your room. They are a great way to eliminate boomy sounds in your music, and improve the overall sound quality of your mixes.

Bass Traps can be constructed from a variety of materials including acoustic foam, fiberglass, and Rockwool. They also come in different thicknesses to help absorb the lower bass frequencies.

These traps are made up of a core absorbent damp material, a frame, and a covering for aesthetic reasons. They are often used in conjunction with absorbers and diffusion to maximize their effectiveness in controlling the sound in your room.

Porous base traps like acoustic foam or fiberglass are great for rooms that need a little extra low frequency control. However, they don’t work as well for a lot of bass frequencies because they are too thin and they don’t reach that deep into the frequency spectrum.

Wall Treatments

Wall treatments are a key design element in a room and have the ability to change the look of a space. They can be a quick and easy way to enhance a room while defining its aesthetic, style, and mood.

A wide range of acoustic wall coverings is available. From fabric-covered acoustic wall panels to textured paint, they can add depth and character to a room and create a focal point.

Using natural materials of soundproofing curtains like grasscloth or oversized woven wood wall panels can add biophilic design elements to your interior. They can also complement a wide range of decor styles and create an eco-friendly look.

If you’re looking for a more traditional style, wainscoting can be a great option. Traditionally, this type of wall treatment features baseboard moulding and chair rails. It’s an excellent choice for a room with hardwood floors or a wooden ceiling. It protects against chair scuffs and is a great design feature to add to your home.
