Acceleration sensors can be used if contacting during the measurement is generally possible and the frequency range relevant to the test can be covered.
Acceleration sensors record structure-borne noise at one point and are therefore independent of ambient noise. Several vibration directions can be recorded (triaxial). A sufficiently good contact with the component to be measured must be established for signal recording.
Acceleration sensors are used, for example, for cost-effective noise testing or vibration testing. Depending on the type, these are usually designed for a frequency range of up to 12 kHz. Depending on the type of contact, the frequency range is significantly reduced.
