The Importance of Home Theatre Acoustics & Your Home Cinema
Often Home Theatre Acoustics are not talked about yet they are one of the most important considerations in a Home Theatre room. It doesn’t matter how much money you spend on equipment, speakers and cabling, without good room acoustics and design it will never give you the best experience you can achieve. A common misconception with Home Theatre Acoustics is that people think its "sound proofing". Sound proofing is just one small part of what Home Theatre acoustics do.
What is the purpose of having good acoustics?
- Provide great audio dynamics
- Provide great imaging from one speaker to another
- Minimal or no interference with the lifestyle of people outside the theatre room
- Lowering the ambient level of noise coming into the Home Theatre Room
- Correct audio issues within the room
Acoustic treatments can be used to improve a rooms performance. Acoustics treatments such as absorber panels are placed in particular positions specific to the room, to help correct audio issues such as delayed sounds, slap echo, Boomy bass and many others.
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 back wall. These reflected sounds take longer to reach your ears effectively making them exaggerated and distorted. 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 to stop these sounds?
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.
You should always talk to an experienced home theatre designer when using acoustic treatment products to make sure you are addressing the specific sound issues of your room.
A basic rule of thumb for treating a room is as follows
- 20% absorptive
- 20% diffusers
- 20% corner area bass traps
There are many other items that need to be addressed when designing a Home Theatre room.
