- Hearing Health Guidelines
The NIDCO (National Institute of Deafness and Other Communication Disorders) offers this simple rule of thumb to prevent Noise Induced Hearing Loss (NIHL): avoid sound exposure that is “too loud, too close, or too long.” Here are some general references to sound levels that occur in everyday life: refrigerator humming (45 dB); normal conversation (60 dB); city traffic (85 dB); motorcycles (95 dB); an MP3 player at full volume (105 dB); sirens (120 dB); firecrackers (150 dB). Damage to your hearing ability could happen in a single event or gradually over time. One- time exposure to sounds louder than 110 decibels and extended exposure to sounds over 85 decibels should at all times be avoided. Indicators of NIHL include hearing loss and tinnitus—a constant ringing, buzzing or roaring in the ears.
- Sound Isolation vs Noise Cancellation
Sound isolation is a passive, physical method of reducing external noise that uses optimized materials and designs to reduce the ambient noise that enters through your headphones. Noise cancellation is an active, electronic method of reducing unwanted ambient sound that adds processed sound to your audio to reduce the perception of ambient noise. Our current headphones achieve very high ambient noise reduction through passive sound isolation techniques, particularly our MW60 and MH40 models with their over-ear design.
