Probe Microphone

Probe Microphone Type 4182 has a smooth frequency response from 1Hz to 20kHz, with a very smooth high-frequency roll-off.

USE SCENARIOS

• Near-field measurement of loudspeakers
• Investigation of sound distribution inside:
• Telephone equipment
• Hi-Fi headphones
• Musical instruments
• Measurement of noise radiation from intricate machinery
• Measurement of attenuation in hearing protectors
• Acoustic impedance measurements

Measurements can be performed extremely close to the sound source due to its small size. Measurement points can be closely spaced when it is necessary to have a high spatial resolution. The high impedance of the narrow probe tip enables measurements in very small volumes – as small as 1cm³ with only minor effects due to acoustic loading.

Physically, our Probe Microphone is very small and lightweight and has a durable construction. Interchangeable stiff and flexible probe tubes, of various lengths, make the probe microphone very adaptable for measurements in awkward places.

For safety reasons, Probe Microphone Type 4182 is not suitable for measurements on the human body.
