Decibel Chart: Complete Sound Level Reference (2026)

The decibel (dB) scale measures sound intensity on a logarithmic scale. Every increase of 10 dB represents a doubling of perceived loudness, even though the actual sound energy increases tenfold.

Below is a comprehensive reference covering the full range of human-audible sound, from the quietest environments to the most extreme sources. Use this chart to understand where everyday sounds fall and when hearing protection becomes necessary.

This chart uses the dB(A) weighting scale, which adjusts for human hearing sensitivity. Most consumer and professional sound meters use A-weighting by default.

Sounds in the 0–70 dB range are safe for hearing at any duration. This covers everything from near-silence to busy traffic and running showers. No hearing protection is needed, though sounds above 50 dB may be considered 'noisy' for sleeping or focused work.

Key reference points in this range: breathing (10 dB), whisper (30 dB), quiet library (40 dB), moderate rain (50 dB), conversation (60 dB), and shower running (70 dB).

Between 70 and 85 dB, sound is loud but not immediately dangerous. Prolonged daily exposure (8+ hours) at the upper end of this range approaches hearing damage territory. The EPA identifies 70 dB as the 24-hour average below which no hearing damage occurs over a lifetime.

Common sounds: vacuum cleaner (75 dB), busy traffic (75 dB), alarm clock (80 dB), garbage disposal (80 dB), blender (85 dB).

85 dB is the critical threshold. Above this level, hearing damage is a function of time. Safe exposure times drop rapidly: 85 dB = 8 hours, 90 dB = 2 hours, 100 dB = 15 minutes, 110 dB = 2 minutes.

Common sounds: lawn mower (90 dB), motorcycle (95 dB), nightclub (100 dB), chainsaw (110 dB), ambulance siren (120 dB). Hearing protection is essential in this range.

Above 120 dB (the threshold of pain), any exposure risks immediate hearing damage. Sounds in this range include gunshots (140–165 dB), fireworks at close range (150+ dB), and jet engines (130–150 dB).

At 140 dB, eardrum rupture becomes possible. At 185+ dB, sound becomes a shockwave that can cause physical injury beyond hearing damage. Rocket launches produce 180+ dB at the pad.

Remember: every 3 dB increase doubles the sound energy, and every 10 dB increase roughly doubles the perceived loudness. Small differences on the chart represent significant differences in real-world impact.
