Hearing loss is one of the biggest health concerns in the U.S. It is the third most commonly reported physical condition, following arthritis<\/a> and heart disease. It affects roughly 20 percent of the American population, and can strike people of all ages.<\/p>\n\n\n\n As we get older, we all experience presbycusis, age-related hearing loss. Because of this, the cells in your ears begin to have trouble picking up higher frequency sounds. In addition to normal, age-related hearing loss, high-frequency hearing loss is caused by:<\/p>\n\n\n\n Those with high-frequency hearing loss find it difficult to hear sounds in the 2,000 to 8,000 Hz range. This type of hearing loss makes it hard for individual to hear s, h or f sounds as well as the voices of women and children. Other sounds people may miss is birds chirping or the beeping of a microwave.<\/p>\n\n\n\n Sound travels in waves and is measured in frequency and amplitude.<\/p>\n\n\n\n Amplitude is the measurement of how forceful a wave is. This measurement is reported in decibels (dB); the louder a sound is the higher the decibel number will be. Sounds that are too loud can permanently damage your hearing<\/a>. Normal conversation clocks in around 65 dB.<\/p>\n\n\n\n Frequency is the measurement of the number of sound vibrations in one second. Measured in hertz (Hz), a healthy ear can hear a wide range of frequencies, from as low as 20 Hz to as high as 20,000 Hz.<\/p>\n\n\n\n 8,000 Hz should be easily heard by everyone with normal hearing What Makes a Sound High-Frequency? <\/h2>\n\n\n\n
