Directional Response Testing - BZ-5551

This PULSE software measures the output of a speaker in all directions and determines the directivity of the speaker’s sound. It presents the results as a polar plot, showing the acoustic levels and frequency response in a circular graph with the speaker in the middle. It also controls a turntable used in order to precisely turn the speaker.

This software adds directional capabilities to PULSE Basic Electroacoustics Type 7797. It can work together with a Brüel & Kjær turntable system, which it also controls. This hardware turns the speaker at precise intervals, so the fixed microphones can build a complete picture of the speaker’s response in 360 degrees. The software also supports manual measurements at different angles.

 

REQUIREMENTS

This software requires PULSE Basic Electroacoustics Type 7797.

ADDITIONAL CAPABILITIES

Our software package PULSE Electroacoustics Type 7907-S1 gives you a complete toolbox for testing. It includes this electroacoustic directional response testing software as standard. See the product data sheet for more information.

  • Audio engineers researching, measuring and documenting acoustical designs during development, pre-qualification and manufacturing
  • Benchmarking the acoustical performance of electroacoustic transducers such as loudspeakers and hydrophones 
  • Evaluating acoustical accuracy of hydrophones, microphones and loudspeakers
