AV rooms are commonly constructed by architects and builders who possess their knowledge and experience.
Creating a perfect home theater room, media room, or commercial space is the most important recommendation.
The following recommended dimensions must be used for the Home Cinema Theater room to obtain the complete Dolby Atmos 7.2.4 format:
To obtain the complete Dolby Atmos 7.2.4 format, the length is 24 feet, the width is 12 feet, and the ceiling height is 10 feet. Dolby Atmos 7.2.2 format can be constructed with a room length of 20 feet, a width of 11 feet, and a ceiling height of 10 feet. The recommended measurements for Dolby Atmos and DTS:X are as follows:
Home theater rooms benefit from using these formats. The Audiophile system cannot operate above 24 feet due to the lack of headroom required for power. A cinema system is the only recommendation.

Sound reflections are caused by dry walls, floors, and ceilings with heavy edge design slopes. These reflections occur when a listener is approximately 3 meters away from the speaker, causing the sound to travel in various directions, hitting walls, floors, and ceilings. This is responsible for reflections, echoes, and resonances in rooms, among other things.
What steps can we take to create a perfect home theater environment? Analyze the sound traveling behavior of the room before installing the audio/video equipment. By blowing a balloon or snapping a wooden stick, a reverb sound can be generated, which can be extended with RT60.
The decay plot area, frequency range, and amplitude color are all present. Our attention should be on proper acoustics and the elimination of timing issues that cause reflection and phase response.
Reflection and corner resonances cause a non-linear response in room time decays, leading to a phase shift of 180 degrees (+-180 degrees) or 360 degrees for each frequency range. It is necessary to adjust its swings to match the degrees of normal flat phase response and implement the proper time filter in DSP delay in milliseconds or seconds using its channel delay functions.

The full-range speaker's frequency response commences at 50Hz and ends at 20KHz. If there is a reflection area within the room, it will lead to significant peak and dip frequencies in specific frequency areas in our analyzer spectrum. To eliminate these issues, follow the digital software-based correction procedure. To correct the dips and peak values of a particular region using PEQ (Parametric EQ), it is necessary to use the correct method.
All modern AV processors and receivers have a GEQ that provides the ultimate in clear sound and linear phase response with correct timing.

To get the most accurate results for optimizing the room, it is necessary to test it with Digital Sound Acoustics Software before treating it acoustically. For a brief analysis of acoustics behavior in the room, almost all of them employ Easera software.
In order to treat acoustics manually, one should place a mirror in front of the speaker close to the side walls. To prevent unwanted reflections, install absorption panels or diffusers where speakers are facing directly to the wall in specific areas.
The corners of the room hold a significant amount of low-frequency sound waves in decay. To eliminate this, install full corner bass traps to shut down and absorb the decay wave and reproduce clean, tight, punchy bass. The best suggestion is to maintain full acoustics treatment throughout the room to achieve a good, optimistic flat sound wave response.
