OPTRT60 RT60 Large Room Decay 60dB
The RT60 Option measures the reverberation time of a room. The RT6030 is use with DSPCIW analyzer. The reverberation time is how long it takes for a sound to decay by 60dB in a room. Measurements taken can be stored and printed. No computer is needed with this option.

The RT60 is a measurement of how long it would take a sound to decay 60dB in a large room. There is great debate as to the value of RT60 in small rooms, or in rooms with an RT of less than 1 second as they are not statistically reverberant. Long RT60 times tends to make it more difficult to understand speech in a room, but may be pleasing for some forms of music. In most rooms RT60 times will be longer at the lower frequencies. The RT60 measurements show both octave band and broadband RT60. In general the octave band information is by far the more useful. RT60 is a powerful tool for predicting intelligibility, and for the selection of type and requirements for acoustical materials. RT60 information also provide guidelines for determining where High Q (directivity) loudspeakers will be essential to maintain intelligibility of speech.

Measurement Frequencies: 125, 250, 500, 1000, 2000 & 4000Hz.
Measurement Range: 0.1 to 10s in 0.01s (1/100ths) increments.
Option Kit Contains: An upgraded EPROM device, a jumper cable to internally connect the circuit board to the front panel and a jumper cable to connect the DSP to an external gate source such as a Gold Line PN3B Pink Noise/Tone Generator.
A front panel overlay is available as a separate option.
