| Question | Answer |
|---|---|
| What is compression? | Area of a medium where matter is close together. |
| In what forms can a medium exist? | A gas, liquid or solid |
| What is needed to create sound? | A vibration |
| What is rarefaction? | An area of a medium where matter is far apart. |
| What words would you use to describe the volume of sound? | Loud or soft. |
| What words would you use to describe the pitch of sound? | High or low. |
| Sound is created when a medium | Vibrates. |
| Pitch is measured by a waves what? | Frequency. |
| Loudness is measured by a waves what? | Intensity. |
| Sound waves travel faster in which medium, liquid or solid? | Solid |
| When the combination of the fundamental tone and the overtones results in a sound with a pleasing timbre and a clear pitch, the sound is considered what? | Music. |
| Sound is a disturbance that travels through a medium as what kind of a wave? | Longitudinal wave. |
| Another word for a person's voice box is ? | Larynx. |
| The speed of sound depends on three different things of the medium. What are they? | Elasticity, density, and temperature. |
| The ability of a material to bounce back after being disturbed is called what? | Elasticity. |
| The mass of a given space or volume is called what? | Density. |
| Does sound travel more slowly or faster at lower temperatures? | Slowly. |
| Does sound travel more slowly or faster at higher temperatures? | Faster. |
| Loudness is measured in what unit? | Decibels (dB). |
| What occurs when the frequency of the sound waves and the natural frequency of the object are the same. | Resonance. |
| What is the apparent change in frequency as a wave source moves in relation to the listener called? | Duppler effect. |
| What word do we use to describe the quality of the sound we hear. | Timbre. |
| What do we call the measure of sound waves with frequencies that do not sound pleasing together? | Noise. |
| What is the word we use when the sounds of music and noise are combined. | Dissonance. |
| When two sounds combined together sound louder than either of the two original sounds, what do we have? | Constructive interference. |
| When two sounds combined together result ina softer sound or one that is completely concealed, what do we have? | Destructive interference. |
| What is the purpose of the outer ear? | To funnel sound waves. |
| What is the purpose of the middle ear? | To transmit the sound waves inward. |
| What is the purpose of the inner ear? | To conver the sound waves in to a form that brains can understand. |
