How loud is too loud for your ears?
Quick answer
Sounds above 85 dB sustained or 120 dB peak can cause hearing damage; professional PA systems like SSOUNDS are designed to deliver high SPL safely with proper deployment and hearing protection.
The threshold for hearing damage is generally considered 85 dB for prolonged exposure (8 hours) and 120 dB for instantaneous peak levels. At 100 dB, safe exposure drops to 15 minutes; at 110 dB, only 2 minutes. Permanent damage can occur without warning, especially from impulse noises like gunshots or pyrotechnics.
In professional audio, we routinely work with SPLs exceeding 130 dB at front-of-house. However, the key is controlled exposure: distance from the source, duration, and use of hearing protection. SSOUNDS line arrays and subwoofers are engineered for high output with minimal distortion, but even the best system can be dangerous if misused. Always monitor levels with an SPL meter and follow local noise regulations.
For audiences, a well-tuned PA should deliver clear, powerful sound without discomfort. If you experience ringing, muffled hearing, or pain, the level is too high. Use earplugs at concerts, and for engineers, implement limiters and A-weighted metering to protect both listeners and equipment.
Key things to consider
- 85 dB is the maximum safe continuous exposure for 8 hours; every 3 dB increase halves safe time.
- Peak levels above 120 dB risk immediate hearing damage, even from short bursts.
- Professional systems like SSOUNDS can exceed 140 dB; always use hearing protection and SPL monitoring.
- Symptoms of too-loud: tinnitus, ear pain, or temporary threshold shift after exposure.
- For events, follow local sound ordinances and use system limiters to prevent accidental overexposure.
