17.4 Sound and Hearing
... In general, sound waves travel fastest in solids, slower in liquids, and slowest in gases. • Particles in a solid tend to be closer together than particles in a liquid or a gas. • The speed of sound depends on many factors, including the density of the medium and how elastic the medium is. ...

Studying Sound and Hearing
... Every day we are exposed to sounds from televisions, radios, and even traffic. Usually these sounds are present at safe volumes that do not affect our hearing. However, when exposed to sounds that are too loud or that last too long, hearing can be damaged. Conduct this simulation to understand how s ...

Low Frequency Sound Insulation by ROXUL
... Frequency (or pitch) refers to how often, or the number of times per second, that a sound wave cycles from positive to negative to positive again. Frequency is measured in cycles per second, or hertz (Hz) from wave trough to wave crest. Technically, 1Hz describes one complete cycle per second of a s ...

... tuning pitch “A” generates sound waves at 440 cycles per second. You can think of this in terms of waves in the ocean — frequency would be the number of waves you can see at one time looking out over the ocean. And like ocean waves, sound waves can be measured by physical length from crest to crest. ...
