PPT-The Decibel Scale

Pain Damage Constant exposure leads to permanent hearing loss The chart below lists the approximate sound levels of various sounds The loudness of a given sound depends of course on the power of the source of the sound as well as the distance from the source Note Listening to loud music will gradually damage your hearing. phon curve.

Objectives. * Explain how sound waves are produced. * Relate frequency to pitch. * Compare the speed of sound in various media. * Relate plane waves to spherical waves. * Recognize the Doppler effect, and determine the direction. }. Constant exposure . leads to permanent hearing loss.. The chart below lists the approximate sound levels of various sounds. The loudness of a given sound depends, of course, on the power of the source of the sound as well as the distance from the source. Note: Listening to loud music will gradually damage your hearing!.

All scale drawings . must . have a scale written on them. Scales are usually expressed as ratios.. Normally for maps and buildings the ratio:. Drawing length: Actual length. For maps the ratio is normally in the ratio:. Scale, Scale Factor, & Scale Drawings. Objective:. 7.2.01 & 7.3.03. Essential Question:. . How can I use a scale factor to understand distances on a map or the size of a house or object?. Vocabulary:.
