  • How Dangerous is Noise

    Hearing Loss

    Hearing loss is one of the most commonly reported physical occupational diseases. Many folks are exposed to dangerous noise levels in their daily work, (typically rock stars) and the tricky part is that it creeps up on you slowly over time; which males it difficult to detect and unfortunately hearing loss is almost always permanent.

    Now for the good news. Hearing loss is preventable. It depends on equipment and you can now see where this is going. The right gear, the right headphones, and the world, so to speak, rights itself and you become redeemed. Bottom line, get the right gear and save your hearing.

    Facts about Sound

    • Sound is vibration causing pressure. It is measured in in decibel (dB) and frequency (Hz).
    • dB is a logarithmic scale. For example, an increase of 3 dB doubles the sound pressure level. The difference between 0 dB and 120 dB, which is the pain threshold, is around 100 billion times.
    • A small increase in dB represents a gigantic increase of noise exposure risk.
    • Frequency is the number of oscillations per second. Humans can hear frequencies between 20-20 000 Hz.
    • The most common sounds, like that of human speech, are found in the mid- to high frequency range (500-4000Hz). This is where human hearing works best, but it is also where your hearing is most sensitive to overexposure.
