When room acoustics properties are at issue, the RT60 reverberation time solution represents an essential tool for obtaining an accurate measurement of reflected sound. The easy setup enables reliable measurement for effective modification of room parameters and easy achievement of desired reverberation time.
Reverberation time is the time required for the sound to “fade away” or decay in a closed space. Sound in a room will repeatedly bounce off surfaces such as the floor, walls, ceiling, windows or tables.
When these reflections mix, a phenomenon known as reverberation is created. Reverberation reduces when the reflections hit surfaces that can absorb sounds such as curtains, chairs and even people.
The reverberation time of a room or space is defined as the time it takes for sound to decay by 60dB. For example, if the sound in a room took 10 seconds to decay from 100dB to 40dB, the reverberation time would be 10 seconds. This can also be written as the T60 time.
In many cases, the ISO 3382 series of standards are used in the calculation of reverberation time. These standards define the methodology to be used when determining the T20, T30, and T60 values as well as the calculation of uncertainty and reliability of the values.
