The term sound <\/em>describes energy that travels in waves. There are two ways to measure these waves: amplitude and frequency. Amplitude is reported in decibels (dB), while frequency is reported in Hertz (Hz). Below we review how amplitudes and frequencies impact your hearing.<\/p>\n\n\n Decibels measure amplitude, which can also be stated as the pressure or forcefulness of a soundwave. The greater the amplitude, the louder the sound. Another way to describe amplitude is volume.<\/p>\n\n\n\n It\u2019s important to know that the decibel scale is logarithmic, or that it increases exponentially. So if there\u2019s a 10 dB increase in sound, it means the sound is 10x louder, while if there\u2019s a 20 dB increase in sound, it means the sound is 100x louder.<\/p>\n\n\n\n Below is a list of common sounds and their decibel outputs:<\/p>\n\n\n\n Hertz (Hz) measure frequency, or the number of sound vibration cycles in one second. We perceive frequency as sounds being high-frequency, meaning there are many cycles per second, or low-frequency, meaning there are fewer cycles per second. Another way to refer to frequency is pitch.<\/p>\n\n\n\n Human ears can detect sounds between 20 and 20,000 cycles per second, or 20-20,000 Hz.<\/p>\n\n\n According to the Centers for Disease Control and Prevention<\/a>, \u201cNoise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.\u201d<\/p>\n\n\n\n While sounds around 70 dB take at least eight hours to cause damage, sounds at 120 can cause instantaneous damage.<\/p>\n\n\n You should always wear some form of hearing protection<\/a> when participating in noisy activities like attending concerts at The Echo<\/a>. If you work in a noisy occupation, your employer should provide you with hearing protection<\/a>.<\/p>\n\n\n\n Types of hearing protection available include:<\/p>\n\n\n\nAmplitude<\/h2>\n\n
