How much time is considered a good amount for acoustic reflection in milliseconds?

A good amount of time for acoustic reflection typically ranges from 10 to 35 milliseconds. This interval is significant because it allows for the perception of reflection without compromising the clarity of the sound. Reflections that occur within this timeframe can enhance the auditory experience by providing a sense of space and depth, helping to create a more immersive environment.

When reflections happen too quickly, such as in the 1-10 ms range, they may interfere with the direct sound, leading to a comb filtering effect that can confuse the listener. Conversely, reflections that occur too late, beyond 35 ms, may be perceived as echoes rather than a coherent part of the audio environment. Such delayed reflections can detract from the quality of the sound and make it harder for audiences to distinguish between direct and reflected sound waves, disrupting speech intelligibility and overall sound quality.

Therefore, the 10-35 ms range is optimal for achieving balanced acoustic reflection that supports clarity and environmental perception.
