Acoustic sensors are used to measure sound and vibration, and for that you must configure a system extending from sensors to final measurement results. Such systems vary in size and complexity. You can use many different combinations of hardware and software, depending on the requirements of your system.

The type of sensor you choose depends on which signal you are measuring. For sound and vibration applications, common signals are acceleration, displacement, and sound pressure level. Common sensors to measure these parameters are accelerometers, proximity probes, and microphones, respectively. You should first know the type of sensor you intend to use, because this largely governs your choice of hardware.

Dynamic range is a measure of how small you can measure a signal relative to the maximum input signal the device can measure. Expressed in decibels, the dynamic range is 20 log (Vmax/Vmin). Thus, the input range and the specified dynamic range are important for determining the needs of your system.

The cost of your individual system depends on the components you use and it is a very important question in selecting any type of sound and vibration measurement system.

Acoustic wave sensors, filters and other similar sensors (mostly ultrasonic) are excluded here because they measure other physical phenomena and not acoustic phenomena albeit they use it on their functioning.
