Question | Answer |
A reflected sound wave | Echo |
The ability of a material to bounce back after being disturbed | Elasticity |
How much matter, or mass, there is in a given amount of space, or volume | Density |
The amount of energy a sound wave carries per second through a unit area | Intensity |
The loudness of different sounds is compared using this unit | Decibel |
The description of how high or low a sound seems to a person | Pitch |
The normal human range of hearing | Ultrasound |
Sounds with frequencies below the human range of hearing | Infrasound |
Known as your voice box and where your vocal cords are located | Larynx |
The change in frequency of a wave as its source move in relation to an observer | Doppler Effect |
What causes the Doppler Effect? | When a sound source moves, the frequency of the wave changes because the motion of the source adds to the motion of the waves. |
What causes a Sonic Boom? | When a shock wave releases a huge amount of energy |
The lowest natural frequency of an object | Fundamental Tone |
The object's higher natural frequencies | Overtone |
The study of how sound interacts with each other and the environment | Acoustics |
Sound waves reflect back and forth off the hard surfaces | Reverberations |
It collects sound waves and directs them into a narrow region | Ear Canal |
Small, tightly, stretched, drum like membrane | Eardrum |
A fluid-filled cavity shaped like a snail shell | Cochlea |
The used of reflected sound waves to determine distances or to locate objects | Echolocation |
A system that uses reflected sound waves to detect and locate objects underwater | Sonar |
The device uses the reflected ultrasound waves to create a picture | Sonogram |
