The Importance of Acoustics in a Home Theater Installation

Get the Best Sound Out of Your Speaker System with Acoustic Treatments

A room may have all the equipment to play the part of a home theater—a large display, surround sound speakers, and cinema seating. But without acoustic treatments, it won’t feel comfortably immersive like a professional cinema should.

When many homeowners assemble a home theater, they skip one of the last steps—acoustics. You might think, It’s fine. What do acoustic panels even do, anyway? Well, without acoustic treatments, some sound frequencies may overpower others and cause reflections, making it difficult to hear,

If you’re upgrading your private cinema or undergoing a home theater installation for the first time, it’s crucial not to forget the acoustics. We’ll share what acoustic treatments do, why they’re important, and how to install them in your Pompano Beach, FL theater.

What Do Acoustic Treatments Do?

Sound covers a broad spectrum— from the deepest, rumbling bass notes to a high-pitched tinkling bell. The human voice falls somewhere in between. But when low frequencies bounce against walls, tones build up in certain areas. Reflections will cancel out some low tones, while other sounds become more pronounced and overwhelm the room. This distorts surround sound audio, making it difficult to understand dialogue and follow a movie’s plot.  

That’s why we need acoustic treatments! Acoustic treatments both absorb and scatter soundwaves through materials like foam and fiberglass. Two to three inches of soft materials on theater walls should be more than enough to absorb speech sound levels. 

Acoustics & Soundproofing: Two Different Treatments 

Many people mistake acoustics and soundproofing for the same thing when they’re two separate concepts. If you want to contain sound inside the home theater and block out exterior noises, that will require special soundproofing solutions. Acoustic foam panels won’t do anything to soundproof your theater. Instead, you’ll need seals around windows and doors and thick insulation within the walls.

Where to Install Acoustic Solutions  

To sufficiently absorb sound reflections, we recommend including foam or fiberglass panels on the walls and using soft carpet floors. If you’re building an open concept media room, heavy curtains, rugs, tapestries, and even house plants can help. Smaller rooms and rooms with equal dimensions need acoustics even more than large rectangular spaces, so consider how your theater’s dimensions may affect sound quality.

Find Balance with Scattering & Diffusion

Did you know it’s possible to absorb sound? In an overly-treated room, the sound may feel ‘dead’ or uncomfortably still. The human ear still needs some sound reflections to sound natural, and diffusion tactics will help keep your room’s audio balanced.


Diffusion is the act of evenly scattering sound energy across a room so that sound waves don’t get stuck in one area. Diffusers often look like geometric or angled shapes. If you’ve ever spotted ridged wooden paneling on walls and ceilings, that’s diffusion! An AV professional will know how to properly treat your home theater with absorption and diffusion materials and arrange furniture for optimal sound results.
