Loudspeakers and entertainment systems can be found just about everywhere: phones, cars, TVs, headphones, computers, toys, public announcement systems, and cinemas.
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:
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.
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.
CCLD Pressure-field microphone for coupler, random-incidence and free-field measurements with 90° incidence and a frequency range of 5 Hz to 20 kHz
Free-field microphone for high-precision, free-field measurements with a wide frequency range/bandwidth of 3.15 Hz to 40 kHz.
Designed for applications where system excitation is required, such as audio and electro-acoustic test applications.
Artificial Mastoid designed for the calibration of bone-conduction hearing aids by simulating the mechanical impedance of the human mastoid.
A compact, highperformance, 2 × 35 W power amplifier designed for electroacoustic and general-purpose applications.
Designed to rotate a test object, such as a loudspeaker, microphone, or hydrophone, for measurement of directional response.
BZ-5602, BZ-5603, BZ-5743 and BZ-5744
Dedicated PULSE testing software applications for specific products including microphones, speakers and headsets.
