The word \u201csound\u201d describes a type of energy that travels in waves. You can measure these waves in two ways: amplitude, which is reported in decibels (dB), and frequency, which is reported in Hertz (Hz). In this post, we review how amplitudes and frequencies impact your hearing.<\/p>\n\n\n\n

What Is Amplitude?<\/h2>\n\n\n

Amplitude refers to the pressure or forcefulness of a soundwave, and can also be described by the term \u201cvolume.\u201d The greater the amplitude, the louder the sound and the higher the decibels.<\/p>\n\n\n\n

The decibel scale is logarithmic, which means it increases exponentially. If there\u2019s a 10 dB increase in sound, it means the sound has become 10x louder, while if there\u2019s a 20 dB increase in sound, it means the sound has become 100x louder.<\/p>\n\n\n\n

Here is a list of common sounds and their decibel outputs:<\/p>\n\n\n\n
