Case Study 01: Home Cinema at Pune

Overview

The Owner of the home cinema is a very passionate audio-video enthusiast. He wanted to refurbish his existing dedicated home cinema room on the first floor of his residence located at one of the poshest locality in Pune, India.

Goal

The existing home theatre’ acoustic treatment was not up to the mark and was not helping the client get the best audio out of his existing, Incredibly talented Active PMC Home theatre system.

The Acoustics of the Home cinema room, including the acoustic wall panelling, Acoustic ceiling and flooring, needed rework. Once rebuilt, the dedicated home cinema room should serve as a perfect place to recline and relax while watching a movie.

The home theater technically needed acoustical treatment to give justice to the existing Hi-End home theatre speaker system from PMC.

Acoustics 

After receiving inputs from the client and the Acoustic design consultant on board, Symphony 440 Design Group Home theater consultants got involved in the home cinema acoustic construction process. Implementations included the following:

1. We started the acoustic construction work with corner Bass trapping behind the home theatre screen that would help in reducing the intensity of the modal resonances.

This particular bass trap, built using high-density Rockwool, Limp Mass membrane, and other approved acoustic materials, helped reduce the ill effects of bass nulls and peaks caused by the room’s dimensions.

2. After the corner bass trapping, We worked on the 1” and 3” thick Acoustic wall Panelling for first-order reflection treatment on the side walls.

These Acoustic wall panels, Built using Sorbermel Melamine acoustic foam, UPVC stretch fabric gripper system, have high absorption coefficients and help achieve better soundstage from the front left & right speakers.

3. Moderately sized home cinema rooms need acoustical diffusion. In consultation with the acoustic consultant, We decided to place Polycylindrical Acoustic Diffusers on the sidewalls to improve the sound quality of the home cinema.

This Acoustic diffuser has a Rockwool of 96kg/m3 as the infill and helps in reducing the intensity of harmful reflections and redirects them to many different directions in the room.

4. Next, We built massive 8” D Limp mass-based acoustic bass traps on the back wall to even out the bass response throughout the listening area in the dedicated home cinema room.

These acoustic bass traps, built using many high-quality Acoustic materials, including Rockwool, Sorbermel Melamine acoustic foam, Limp mass membranes,  look as good as they sound.

5. Premium quality melamine acoustic foam wall panels are placed on the side walls to absorb excess sound energy in the room.

6. Acoustical treatment is done on the ceiling using Knauf Danoline boards with other acoustic materials of different thickness and densities placed behind them.

Since the Acoustical ceiling board has perforations of varying sizes, it creates a great aesthetic appeal while ensuring excellent acoustics.
