|---|---|---|---|---|---|
| The mechanical or electronic process of making a sound louder. | amplification
🗑
|
||||
| The continuum of all possible sound frequencies. | acoustic spectrum
🗑
|
||||
| The scientific study of understanding and controlling how sounds are heard; the acoustic properties of a room or building. | acoustics
🗑
|
||||
| A non-SI unit of loudness; the ratio of the power of a measured sound to a reference sound expressed on a logarithmic scale. | decibel
🗑
|
||||
| The biological or artificial use of acoustic echoes to detect distance and direction of objects of interest. | echolocation
🗑
|
||||
| A sound with a frequency below the range audible to humans. | infrasonic waves
🗑
|
||||
| The power of a mechanical wave, proportional to the square of the wave’s amplitude; a wave’s rate of energy transmission. | intensity
🗑
|
||||
| The response of the ear and brain to the intensity of a sound. | loudness
🗑
|
||||
| The property of an audible sound determined by its frequency. Higher frequencies have higher pitches. | pitch
🗑
|
||||
| The ear’s interpretation of the mixture of fundamentals and harmonics in a complex sound, as from a musical instrument. | quality
🗑
|
||||
| An artificial device that either listens passively or uses active echolocation in bodies of water for navigation, research, or military purposes; an informal name for any natural use of echolocation, such as with bats. | sonar
🗑
|
||||
| The form of wave-transmitted energy detectable by the ear; more generally, energy transmitted through matter by mechanical waves. | sound
🗑
|
||||
| A sound with a frequency above the range audible to humans. | ultrasonic waves
🗑
|
||||
| In longitudinal waves, regions of maximum particle density | Compression
🗑
|
||||
| In longitudinal waves, regions of minimum particle density | Rarefaction

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
