Brüel & Kjær Launches Type 4988-A 1/4" Pressure-Field Measurement Microphone
Bruel & Kjaer has a new miniature microphone ideal for high-precision acoustic measurements tests within confined spaces – Type 4988-A. A mini, yet mighty microphone, this new 1/4" low noise, prepolarized, all titanium microphone was designed to help engineers and acousticians achieve accurate measurements in everyday tasks. The new Type 4988-A is flat from 20Hz to 20KHz (±1 dB) and can be used close to hard reflective surfaces, or very close to sound ports of an audio device.
