![]() ![]() This is the reason why sounds that measure high up on the decibel scale are so concerning to our hearing health. Therefore, a sound of 100dB is a billion times more intense than a sound of 10 dB (not ten times more)! How Loud is Too Loud? On the decibel scale, every increase of 10 dB, sound energy is 10 times more intense. If you increase distance from 10 feet to 20 feet for example, that’s double the length. This is an important distinction to understand. To compare noise more simply from one environment to another, the decibel scale is a logarithmic, or exponential scale – not a linear scale. Devices like this display a measurement of sound intensity in units called decibels, a scale first devised by…. These instruments measure sound levels by calculating the pressure of the sound waves traveling through the air from the source of noise. The intensity of the sound is measured by a sound pressure level (SPL) meter. What makes one sound seem louder than another is the amount of energy the source of the sound is pushing towards the listener in the form of pressure variations in the air. In any environment, repeated exposure to loud noises will cause hearing loss, especially over time. To better understand the effects of noise exposure on our hearing health, let’s look at how sound intensity is measured, what’s considered dangerous, and what we can do about it. This should be no different when we’re at work. Hearing loss is most often permanent, so the only thing we can do is be aware of when we’re exposed to too much noise and take precautions to protect ourselves. Unfortunately, most people don’t take their hearing health seriously enough. workers is still caused by occupational exposures. Surprisingly, more than 53% of these affected workers reported not wearing hearing protection, and currently, about 24% of the hearing difficulty among U.S. have been exposed to harmful noise on the job, and over 22 million within the last year. According to the CDC, about 25% of workers in the U.S. ![]()
