| amplitude | height or depth of wave |
| compressional wave | medium vibrates in same direction as wave |
| crest | high point of wave |
| frequency | number of vibrations per second |
| intensity | loudness of sound |
| interference | waves reacting to each other |
| loudness | strength of a sound wave |
| medium | material or area through which a wave travels |
| music | sounds with pleasing pitches and quality occurring in a regular pattern |
| noise | unwanted sounds with irregular pitches |
| pitch | the highness or lowness of a sound |
| quality | describes the differences among sounds of the same pitch and loudness |
| resonance | vibrations that are the result of an objects natural frequency |
| reverberation | repeated echoes |
