Sound Measurement

Intro to Audiology

Amplitude The maximum displacement of the particles of a medium; the distance between the baseline and the maximum displacement.
Aperiodic Wave A wave with an absense of periodicity, where it is impossible to predict what the wave will look like from one time to the next. Its vibratory motion is random.
Complex Wave Any sound that is not sinusoidal; it itself is composed of a series of simple sine waves that can differ in amplitude, frequency, and phase.
Energy The measure of the capacity to do work OR something that can produce a change in matter.
Fourier Analysis Takes a complex wave form and decomposes/analyzes it to determine the amplitudes, frequencies, and phases of its sine wave componants.
Frequency The number of cycles completed per second.
Logarithmic Scale One unit on the scale is so many times greater (or less) than another; successive units are always different by some constant ratio, and the constant ratio always equals the base.
Period The time (seconds) it takes for a vibration to complete one cycle of vibration.
Wavelength The distance traveled by a sound wave during one period of vibration.
Waveform A graph in which changes in pressure or amplitude (displacement), are shown as a function of time.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
