Welcome to our ultrasound microphones page!
Ultrasound microphones are a specialized type of microphone that is specifically designed for detecting sounds in the frequency range of up to 100 kHz and up to 168 dB sound pressure level. These microphones are commonly used for a variety of applications, such as measuring sound in industrial settings, monitoring the health of animals, and testing the performance of audio equipment.
The IEC 61094-4 WS3F is a globally recognized standard for ultrasound microphones, which outlines the specific performance parameters that these microphones must meet in order to be considered accurate and reliable. These include factors such as sensitivity, frequency response, dynamic range, and noise floor.
If you’re looking for an ultrasound microphone that meets these standards, there are a variety of options available on the market today. When selecting an ultrasound microphone, it’s important to consider the specific requirements of your application in order to choose the best possible option for your needs.
