Sound level $L_{P}$ in units of decibles (dB)is determined by:
$L_{P} = 20 \log_{10} (\frac{P}{P_{0}})$
where p is the sound pressure of the sound, and $p_{0} = 20 * 10^{- 6} P a$ is a reference sound pressure (the sound pressure when $L_{P} = 0 d B$ ). Determine the sound pressure of 90 dB noise (noisegenerated by a passing truck). By how many times the soundpressure of the truck is larger (louder) than the sound pressureduring normal conversation where the loudness is 65 dB?

Under what conditions would we hear no sound?

Sound waves are a type of energy that travels through the air, or any other medium, like water or metal. They are created by vibrations, which are produced when something vibrates. The vibrating object causes the air around it to vibrate too. Sound waves are usually described by how fast they vibrate, or their frequency. The faster the vibration, the higher the pitch of the sound. The slower the vibration, the lower the pitch. They can solve problems in physics. For example, equations can be used to calculate the speed of sound waves. Answers to questions about waves and sound can also be found by using sound waves.
