If you want to go all out to make the space where you install your home theater as luxurious as possible, another way to get there is by installing acoustic panels on the walls. Acoustic panels are typically made of foam or wood wool and help dampen excessive echo/reverberation to produce a cleaner, less cluttered sound. Acoustic panels should be strategically placed both in terms of number and location. Lower numbers allow for more intensive use, higher numbers allow you to completely soundproof a room and prevent sound from escaping elsewhere.
All acoustic panels available for purchase will have a Noise Reduction Coefficient (NRC) rating listed on the packaging or in the product description. The NRC rating indicates how much sound a panel absorbs. For example, a rating of 0.65 means that 65 percent is absorbed and the remaining 35 percent is reflected or diffused into the space in which the panel is installed. This diffusion is necessary for good results, as absorbing all sound would muffle the sound.
Acoustic panels not only reduce excess reverberation and improve sound clarity, but also allow viewers/listeners to better perceive the direction of sound. This provides a better surround sound experience. However, the best results come from strategically placing different types of panels depending on location, and combining absorbing panels, diffusing panels, and specially designed bass traps to control low-end frequencies. will be done.
