Home Theatre Acoustics and Your Home Cinema
Home theatre acoustics are an important element of any home theatre design. It doesn’t matter how much money you spend on equipment, speakers and cabling, without good room acoustics and design, your surround sound system will not perform at its best. A common misconception about home theatre acoustics is that "sound proofing" is only consideration. However, sound proofing is just one small part of home theatre acoustic design.
McCormick Concepts considers home theatre acoustics as a fundamental aspect of home theatre design. When designing a home theatre system, we consider the shape and size of the room, the placement of doors and windows, the material used to construct the room (e.g. brick, plasterboard) and the placement of furniture, including soft furnishings. This enables us to determine the appropriate acoustic treament required to offer our clients the absolute best auditory experience.
What is the purpose of having good acoustics?
- Provides great audio dynamics
- Provides great imaging from one speaker to another
- Minimal or no sound interference outside the theatre room
- Lowering the ambient level of noise coming into the home theatre room
- Corrects any audio issues within the room
Acoustic treatments can be used to improve a room's acoustic performance. A room can exhibit a number of acoustic issues, including delays, slap echos, boomy bass and many others. Acoustics treatments such as absorber panels are placed in particular positions specific to the room. to help correct these issues. Our home theatre designers will consider the multiple issues that impact a room's acoustic quality, and will tailor a solution that optimises sound quality.
So How Do Acoustic Treatments Work?
Sound does not just travel straight from the front the speaker to your ears. The sound also “reflects” off other surfaces in your room such as the ceiling, floor, side walls and the back wall. These reflected sounds take longer to reach your ears, effectively acting as multiple echos. This can make the bass sound boomy and dialogue difficult to understand. By carefully positioning particular acoustic treatments you can decrease these effects making the audio crisp, clear and pleasing to your ears.
So why not just use absorptive acoustic material over the whole room?
If you were to hang a thick curtain around all the walls in the room and treat the ceiling and floor with absorptive materials you would effectively make the room sound dead. Your ears will also trick you into thinking the room is much smaller than it is and you will need much more efficient speakers and a more power amplifier to get your room up to THX reference level. This would be a very expensive exercise and not very effective.
A basic rule of thumb for treating a room is as follows:
- 20% absorptive
- 20% diffusers
- 20% corner area bass traps
However, you should always talk to an experienced home theatre designer to make sure you are addressing the specific sound issues of your room. McCormick Concepts are industry leaders in home theatre and surround sound design, and we are committment to supplying theatre and audio systems that utilise the latest technology and reseach.
