What is the minimum dB for a fire alarm?
This gives an acoustically significant safety margin of a factor of 3.1 times when 5 dBA over the required 15 dBA code minimum is present, due to the nature of sound pressure increase in ratio with audible acoustic intensity.
Can a fire alarm hurt a dog’s ears?

How long can you listen to 100dB
Deafness and hearing loss: Safe listening
| Sound intensity in decibels | Time for safe listening per week (7 days) | Example of type of sound at the specified intensity |
|---|---|---|
