Decibel (dB) that we commonly know is called “sound pressure level (S.P.L.)” in the professional terms. It’s the pressure of the sound wave that brings to our eardrum. Generally, the 120dB sound could cause earache. If we stay at the environment with 80dB sound over a long time, our hearing would be probably lost. The lost hearing can’t be recovered anymore. Therefore, to be aware of the sound pressure level is essential to protect our hearing.
The max. S.P.L. of BXB’s column speaker is 105dB, which can totally lower the risk of hearing damage. Moreover, its 180° (horizontal) and 150° (vertical) dispersion is greatly adaptable to the semi-outdoor scenario. It’s the best solution making listeners hear clearly without turning up the volume.
