• Specifications may be subject to change without prior notice
- Sound pressure level is obtained in an anechoic room.
- Sound pressure level is a relative value, depending on the distance and acoustic environment.
- Sound pressure level may differ depending on operation condition.
- dBA = A-weighted sound pressure level
-
Reference acoustic pressure 0 dB = 20μPa
