Hearing Protection
Hearing Protection is only available on specific dBAir models and is an internally stored
database of leading manufacturers hearing protectors.
Selecting Hearing Protection allows you quickly and easily to identify which hearing
protector would suit a specific noise environment after analysing your measured data.
All the assumed protection values calculated are colour coded allowing you to instantly
see if the hearing protector offers the right amount of protection: -
APL Value
<=70dB
70 to 80dB
80 to 85dB
>=85dB
It is highly recommended that over protection where levels at the ear are below 70dB
are avoided. Over protection can impact on communication causing the user to remove
the protection and also reduce the ability to hear warning signals such as fire alarms.
