Do Jabra Multiuse solutions protect users against noise?
Yes. The Jabra Bluetooth hub/adapter protects against loud sounds (e.g. the high-pitched squeals of a fax machine that may be harmful). Many acoustic experts define acoustic shock as exposure to levels in excess of 135 dB SPL, but even lower can damage the ears. Therefore, Jabra Multiuse solutions cut off sounds at 118 dB SPL (RMS).
