A higher decibel indicates a higher level of pressure, or a louder sound. High or low pitched, the decibel measures the intensity of the sound wave and the level of pressure it creates in the ear. Increased velocity will create a higher pitched tone, while a lower velocity sound wave creates a lower-pitched tone. Our ear can measure the tone level of a sound with the velocity and frequency of the sound wave. 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. Whether it’s hearing the waves crash on the beach or listening to the first cries of a child, our sense of hearing is one of the most miraculous and important aspects of life.
