Cinema Acoustic Upgrade
Reverberation is probably the most recognized characteristic of a room’s sound. Reverberation is the acoustic energy in the space that lingers on after the sound stimulus has been removed. Each room’s reverberation times at each frequency are as unique as a signature. Ideally, we want the reverberation times to decay at the same rate across the audible bandwidth, and within a time window of about 0.25 – 0.35 sec. This allows for neutral sound conditions. An exception is for frequencies
below about 100 Hz., where we need slightly longer decays in order for our brain to make sense of the difference between what our ears hear vs. what our eyes see. Lack of reverberation control results in masking of low-level details, loss in dynamic range, soundstage, timbre and articulation.

Home Recording Studio
“It was such a pleasure to work with Norm and Harry on the design on my new studio. The results have exceeded my expectations. Comparing my old room with the new is night and day. I immediately noticed improved imaging with individual instruments occupying specific places within the stereo spectrum instead of being generally panned to the right or left, improved tonal balance, and improved dynamics. In short, my mixes are translating better than ever and with less work. Awesome!
As construction began on the project, the “facts on the ground” made it necessary for Norm to adjust the room dimensions at the last minute when our contractor realized a structural beam prevented the HVAC ducting from being placed where original spec’ed. Norm was able to come up with a solution quickly – allowing our contractor to get back to work.
I highly recommend A/V RoomService.”.

Reverberation is probably the most recognized characteristic of a room’s sound and the most difficult to control. Reverberation is the acoustic energy in the space that lingers on after the sound stimulus has stopped. Each room’s reverberation times at each frequency are as unique as a signature. Ideally, we want the reverberation times to decay at the same rate across the audible bandwidth, and within a time window of about 0.25 – 0.40 sec. This allows for neutral sound conditions. An exception is for frequencies below about 125 Hz., where we need slightly longer decays in order for our brain to make sense of what our ears hear vs. what our eyes see. Lack of reverberation control results in masking of low-level details, loss in dynamic range, soundstage, timbre and articulation.
