How loud is a motorcycle?
A motorcycle measures about 95 dB, roughly as loud as riding a subway. At 95 dB it is at or above the 85 dB line where hearing damage starts: NIOSH puts the safe limit at about 48 minutes a day. Normal conversation runs about 60 dB for comparison.

How a motorcycle compares
On the decibel scale, 95 dB sits above the 85 dB line where sustained exposure damages hearing. Sounds at a similar level:
- Riding a subway 90–95 dB
- Shouted conversation 90 dB
- Car horn at 5 m 100 dB
- Approaching subway train 100 dB

Is a motorcycle dangerous to hearing?
Yes — at 95 dB, a motorcycle is loud enough to damage hearing over time. NIOSH limits safe exposure to about 48 minutes a day; use hearing protection beyond that.
