ISP 215 Chapter 5: The Science of Sound Chapter 5 Notes
Document Summary
Chapter 5: sound waves the first step in an acoustical event is a vibration the second step is the propagation of that vibration. Vibrations are propagated by means of sound waves there are many different kinds of waves. Radio waves, light waves, x-rays, waves on the surface of a lake, and sound waves. A wave can be thought of as a physical means of propagating energy, momentum, and information without transporting mass. Sound waves can travel through solids, liquids, and gasses. Atmospheric pressure is about (cid:883)(cid:882)(cid:2873) or 100,000 pascals. Atmospheric pressure is equivalent to 14. 7 pounds per square inch the o(cid:374)ly (cid:396)easo(cid:374) that you"(cid:396)e (cid:374)ot s(cid:395)uashed (cid:271)y that p(cid:396)essu(cid:396)e is that you(cid:396) i(cid:374)sides a(cid:396)e pressurizes too. Your entire vascular system is pressurized equivalently. A sound wave is a small disturbance in air pressure. Where a sound wave has a peak, the air pressure is slightly greater than atmospheric pressure.
