Electroacoustic Testing
Manufacturers of electroacoustic equipment such as loudspeakers, microphones, telephones, headsets, hearing aids, hydrophones, etc., have, for many years, successfully developed new innovative acoustical designs and introduced these into the market in the form of high-quality products.
One important reason for this success is their ability to continuously improve the products and processes. A key element in this improvement process is the ability to measure and document the acoustical performance, during both the development and the manufacture of new products.
In the future, the ability to characterise electroacoustic equipment using traditional performance specifications such as frequency response, distortion, linearity, directivity, delay, etc., will have to be combined with a wide range of other acoustical and vibration measurements.
Acoustic and vibration measurements such as those performed in material testing, modal analysis, etc., are expected to become a very important prerequisite for continued innovation and improvement within the development and manufacturing of electroacoustic equipment.
PULSE Electroacoustics Type 7907
PULSE Electroacoustics Type 7907 provides a versatile platform for the evaluation of electroacoustic transducers. This includes a wide range of advanced analysis capabilities required by any audio engineer working within the field of research and development of acoustical designs.
With PULSE Electroacoustics Type 7907, various important features of an electroacoustic transducer can be determined. This include features such as output response, frequency response, harmonic distortion, intermodulation distortion, difference frequency distortion, directivity, loudness rating, etc.
Combining PULSE Electroacoustics Type 7907 with one of the high-quality PULSE hardware front-ends reveals the ideal audio analyzer platform. Furthermore, this platform can be expanded by adding software packages to support vibration analysis, sound quality evaluation, data management, and advanced time data recording and analysis.
