Hear the Difference of Noise Control

How to Use These Sound Demos

Use high-quality headphones for the most accurate sound comparison.

The following clips demonstrate the relative differences in sound levels and characteristics to assist in understanding the subjective effects of soundproofing and reverberation control.

Baseline Audio

This playback file serves as a reference level for comparison.

-3 dB Reduction

A modest reduction demonstrating a very subtle but noticeable change in sound level, representing a 50% reduction in sound power as compared to the reference level.

-6 dB Reduction

This represents another 50% reduction in sound pressure from the reference level, resulting in a significant but not dramatic subjective reduction in noise.

-10 dB Reduction

This represents what most listeners consider to be "half the subjective volume" as compared to the reference level.

-20 dB Reduction

Approximately ¼ the subjective volume of the reference level.

Reverberation Time Demos (RT60)

Reverberation time (RT60) measures how long sound takes to decay by 60 decibels after the source stops. Different environments have different reverberation needs: too long, and clarity suffers; too short, and the room seems "dead". Compare the clips below to hear how reverberation time shapes the acoustic character of a room.

Arena – 5000 ms (5 Seconds)

Large arenas often have very long reverberation times, creating echo and reduced speech clarity.

House of Worship – 2000 ms (2 Seconds)

Many worship spaces are designed with moderate reverberation for music, but excessive reflections can make sermons harder to understand.

Lecture Hall – 1300 ms (1.3 Seconds)

Once reverberation extends beyond 1 second, spoken words can overlap, leading to listening fatigue.

Lecture Hall – 800 ms (0.8 Seconds)

Slightly longer decay can still work for small lecture halls, though clarity begins to diminish. Good for bars and casual dining.

Lecture Hall – 600 ms (0.6 Seconds)

A short reverberation time supports clear speech intelligibility, ideal for classrooms and lecture halls. Best for intimate restaurant environments.
