Hearing loss affects more than 48 million Americans. Most have trouble hearing the chirping of birds and the voices of women and children. But for a small group, their hearing loss<\/a> affects their ability to hear low-frequency sounds.<\/p>\n

How You Hear Sounds\"City<\/h2>\n

When you hear your doorbell ring, there is a complex process that happens in order for your brain to know your delivery from Black Tap<\/a> has arrived.<\/p>\n

The soundwave from the doorbell enters your ear and is funneled through the ear canal where it hits the eardrum. This creates a vibration, which is passed through the small bones in the middle ear until it reaches the cochlea. Within the cochlea, located in your inner ear, there are delicate hair cells. These cells are responsible for converting the vibration into an electrical impulse. This impulse is sent via the auditory nerve to the brain where it is processed as sound.<\/p>\n

Types of hearing loss are classified by the point in the hearing process that the problem originates. Conductive hearing loss occurs when there is a problem in the outer or middle ear. Sensorineural hearing loss occurs when there is an issue in the inner ear or auditory nerve.<\/p>\n

How Sounds Are Measured<\/h2>\n

Sounds move through the air in waves. Each soundwave has a specific frequency and amplitude.<\/a><\/p>\n

A soundwave\u2019s frequency, also called its pitch, is a measurement of the number of times per second it repeats itself. Hertz (Hz) is the unit of measure used for frequency. A human with normal hearing can hear sounds between 20 Hz to 20,000 Hz. Someone with low-frequency hearing loss would have trouble hearing sounds measuring 2,000 Hz or lower. These sounds may include:<\/p>\n
