The end user has strong and clear ideas of the performance expected from a product, so it is crucial to transform these expectations into products that satisfy customers. Sound quality measurements help to ensure that customer preferences are met and provide a way to differentiate the product. However, sound quality is not the only parameter a manufacturer may want or need to evaluate:


  • Target setting – Are response, distortion, impedance, sensitivity, directivity, and other values where they need to be?
  • Acoustic material – How do lighter, more durable and less expensive materials affect the sound?
  • Structure – How does a change in cabinet or component design affect the vibrational and acoustic properties of a speaker?
  • Production – Can a manufacturer rely on pass/fail results and receive a quality product?

The number of tests involved in the verification of performance specifications and requirements can be overwhelming for an R&D engineer with a deadline and budget to meet. That is why in the industry, standardization, automation, data correlation and ease of use are such hot topics in R&D testing. Providing these features without compromising reliability and precision, means engineers can meet their targets quickly and efficiently.

System Suggestion

loudspeaker testing

For loudspeaker testing we recommend PULSE Loudspeaker Test Application BZ-5603. This software supports measurements on loudspeakers, using an instrumentation set-up that includes a turntable to automatically record the directional characteristics of the test object. This application automates measurements of frequency response, harmonic distortion, directional response and calculation of Thiele-Small parameters using the simple impedance, added volume, added mass or laser methods.
