Sound Power Testing

Industrial Device Test Solution

The sound power of a source is the total power emitted by that source in all directions. The dedicated Sound Power Test System measures all required data and generates professional measurement reports.

At a Glance

  • Professional analysis and reporting
  • ISO 3741, ISO 3744, ISO 3746 and 2000/14/EC
  • ANSI-ASA S12.51, S12.54, S12.56

Overview

The XL2 Sound Level Meter in combination with the Sound Power Reporter Software forms the professional solution for sound power measurements. The XL2 measures the noise spectrum of the device under test. Additionally it records the ambient noise and reverberation time RT60 for the required corrections. The Sound Power Reporter Software aggregates all data and provides the sound power in dB (reference to 1 pW).

XL2 Measurement Functions

Real Time Analyzer RTA

The XL2 Sound Level Meter measures and logs wideband values and the real time spectrum in 1/1 or 1/3 octave band resolution in accordance with IEC 61260 class 0. The sound level meter results of the wide band and RTA spectrum are simultaneously available.

RT60 Reverberation Time

The XL2 measures the energy decay in the range from 63 Hz to 8 kHz by the Schroeder method in 1/1 octave bands. Automatic triggering and averaging of multiple measurements simplifies the operation and minimizes the measurement time. Use either an impulse source or an interrupted pink noise as the test signal. The optional Extended Acoustic Pack extends the RT60 measurement to a 1/3 octave resolution.
