Inside a kennel: Chorus of barking dogs can reach 115 decibels
Hearing protection programs are designed to reduce the risk of long-term damage from repeated or prolonged exposure to noises. OSHA standards require a hearing protection program when workers are exposed to noise levels above 85 decibels (dB) based on an eight hour time-weight average (TWA). The TWA is a method of calculating the danger based on the intensity of the noise and the duration of exposure, e.g., the louder the noise, the shorter exposure is permitted.
The hearing conservation program can take many forms, including medical evaluations and periodic audiograms for employees, safety equipment, reduction in noise levels by absorption or dissipation, training of employees, and posting of warning signs identifying noise hazard areas. As a general rule, most animal hospitals can maintain a very effective program with a minimum of time and resource expenditures.
