Quest Technologies, Oconomowoc, Wis, a 3M company, introduces the reverberation option for the for the SoundPro SE and DL 1/1 and 1/3 models of advanced sound level meters.

Reverberation time, or RT60, is used to measure sound decay and evaluate the acoustical comfort within a specific space, says the company. The new option enhances the units’ advanced functionality, while measuring in accordance with IEC 61260, ANSI S1.4, and conforming to ISO 3382, says a statement released by the company.

The option offers the ability to choose interrupted or impulse noise excitation to measure reverberation time. The octave band or third-octave band RT60 measurements are displayed in a tabular, decay, or bar chart view on the SoundPro’s LCD screen for the current and session (average) measurements. Spatial averaging can be performed through ensemble or measurement averaging, says the company.

The measurement option is suited for those testing acoustical comfort in factories, transportation terminals, auditoriums, classrooms, gymnasiums, and other large enclosures, says the company. Performing measurements can be done by those with varying levels of expertise, through automatic parameter selection, or manual selection for more advanced users.

The SoundPro SE and DL 1/1 and 1/3 with Reverberation is compatible with QuestSuite Professional II software for in-depth analysis of data with charting, graphing, and report printing.
