Machine noise localization - Sound localization

Machine noise localization with  ES12 Electronic Stethoscope.

It is an advanced technology system designed to help you locate sources of sound quickly and accurately.

The system consists of a directional microphone and an accelerometer that work together seamlessly to detect even subtle vibrations and sounds.

You do not need any special knowledge or training to use this product as it is intuitive and easy to use.

The ES12 is great for diagnosing mechanical problems in engines, HVAC systems and other machinery. 

It also comes with a comfortable and robust headset that allows hands-free operation and gives you more flexibility and control. 

With the ES12 Electronic Stethoscope, you can quickly and efficiently pinpoint the source of unwanted noise, saving you time and money on maintenance and repairs.

AV14 Charge and IEPE Amplifier

The 1-channel charge amplifier AV 14 has been constructed mainly to monitor acoustic and vibration signals. 

It has a measuring channel for an electret condenser microphone or a piezoelectric accelerometer. 

The switching over from the accelerometer to the microphone comes automatically, when the microphone mini-jack is plugged in at the output socket you get a voltage proportional to the acceleration or sound pressure independent of the amplification of the headphone amplifier. 

So the instrument can be used as a front end for analyzers or similar instruments.

KH10 Dynamic headphones

The KH10 is a closed dynamic headphone designed for critical music and sound monitoring in an open environment. The headphones have a frequency response of 5 Hz to 30 kHz and are tuned to the diffuse sound field.

The single-sided 3 m connection cable is equipped with an inline volume control for optimal adjustment. It is equipped with a gold-plated mini stereo jack plug (3.5 mm) with 1/4″ adapter (6.35 mm) and is therefore suitable for use with almost all headphone amplifiers.

The robust headband construction has been reinforced to give the headphones a very secure fit, coupled with mechanical reliability. Soft, easy-to-clean ear pads and adjustable, sliding ear cups ensure a high level of listening comfort even during prolonged use.


  • Closed diffuse-field headphones
  • Excellent attenuation of ambient noise (better than 35 dB A)
  • Excellent audio quality with high sound pressure level (105 dB)
  • Robust spring steel headband
  • Single-sided cable (straight cable, 3 m long) with integrated volume control
  • Gold-plated jack plug (3.5 mm) and adapter (6.35 mm)
