How loud is a dog bark?
A dog bark typically measures 90 to 100 decibels about a metre away, with large breeds reaching higher. The level drops quickly with distance, so the same bark heard from across a garden is far quieter than one beside your ear.

Typical sound level
| Sound | Typical level | Measured at |
|---|---|---|
| Single bark, medium to large dog | 90–100 dB | About 1 metre from the dog |
How it compares to other sounds
| Level | Typical sound | Safe daily exposure |
|---|---|---|
| 70 dB | Vacuum cleaner, busy office, shower | No exposure limit |
| 85 dB | Heavy traffic, noisy restaurant, gas lawn mower | 8 hours |
| 90 dB | Hair dryer at close range, blender | 3 hours |
| 100 dB | Nightclub, handheld drill, sporting event | 15 minutes |
Rows are taken from the full decibel chart. Safe exposure follows the NIOSH recommended exposure limit of 85 dBA for eight hours with a 3 dB exchange rate.
Can this level affect your hearing?
A single bark is brief, so it is unlikely to damage hearing on its own. Repeated close-range barking — in a kennel, a shelter or a car — is a different matter, because the dose accumulates across the day. At 100 dB the safe daily total is only a few minutes of actual sound.
