![]() ![]() Named after Alexander Graham Bell, this unit was created to measure the pressure or power of sound waves. Sound is measured in a unit called Decibels. These bones cause motion in the cochlea and inner ear fluid, creating sound. The eardrum will vibrate as the sound waves make contact, prompting the three inner ear bones to move. The outer ear then sends the waves down the canal, to the eardrum. When something in nature creates a sound wave, the outer ear collects the waves as they come in contact with the ear. Increases or decreases in frequency, velocity, or intensity levels of these waves cause different sounds to be heard. Hearing occurs due to exposure to varying levels of sound waves caused by stimuli in our environment. When someone experiences hearing loss, the impact can be just as monumental. ![]() Humans and animals alike avoid danger, experience the world around them, and express emotion, all through the power of the auditory system. The process of hearing is one of the most beneficial and interesting feats in nature. To avoid damaging exposure and increase the health of your hearing, find out the safe decibel levels for humans and learn to measure decibel intensity level in the average sounds around you. One of the most common ways someone can damage their hearing over time is through exposure to high levels of sound decibels. Like anything else, our hearing requires knowledge and safety to increase its average longevity and maintain the health of our auditory system.

Soundwave Hearing Clinic is proud to provide hearing solutions to residents of Calgary, Grande Prairie and surrounding areas. Keep in mind that the volume on most handheld devices goes up to 80dB and above. You should also avoid listening to music at high volumes, especially while wearing headphones. If you work in a noisy environment or often attend live concerts, it’s important to wear some form of hearing protection. For instance, you’re likely to experience permanent hearing loss after being exposed to a sound of 85dB for eight hours, but you risk permanent hearing damage after only 15 minutes of exposure to 100 dB. Hearing loss occurs as a result of how loud a sound is and how long you’re exposed to it. How high-decibel sounds cause hearing loss Here are the approximate decibel levels for some everyday sounds: Over the course of a day, you hear noises that register at all different points on the decibel scale, from wind rustling in the trees to cars honking in the streets. While decibels are most commonly used to measure sound, they also have applications as a measuring unit in the electronics and telecommunications industries. This is because the decibel scale was developed so that the first telephone companies could represent the amount of signal loss in phone lines. Each decibel involves an increase of approximately 26%, which is roughly the smallest change in sound that the ear can detect.Ī decibel is one-tenth of a bel, a rarely used unit named for Alexander Graham Bell, the inventor of the telephone. As a result, the decibel scale can range from 0 dB to 150 dB and still accommodate all the sound levels that humans hear. This means that a sound that’s 100 dB is not 10 times more intense than 10 dB, but rather 1,000,000,000 times more intense. On a logarithmic scale, values increase by powers of ten. If you tried to represent the full scope of human hearing using a linear scale, you’d need to use a range of sound levels from 0 to 100,000,000,000, which is far too vast to be useful. Decibels as a measure of sound intensityīecause human ears can hear noises with both very small and very large pressure waves, sound intensity needs to be measured using a logarithmic rather than linear scale. Keep reading to learn more about how decibels are calculated and what kinds of sounds can lead to hearing loss. In audiology, we use decibels when testing people’s hearing and identifying which sounds can damage human eardrums. A decibel is a unit of measure that compares two power levels, most often used when talking about sound intensity. ![]()
