Study Notes
Sound Energy
- Sound is a type of energy that travels through the air in waves and can be detected by hearing.
Mechanism of Hearing
- When sound waves reach the ears, they create vibrations that are processed by the brain, allowing us to perceive sound.
Sources of Sound
- Common sources of sound include musical instruments, human voices, animal calls, and mechanical devices.
Eardrum Response
- The eardrum vibrates when sound waves hit it, translating these vibrations into auditory signals for the brain.
Sound Travel Medium
- Sound travels through various mediums, including air, water, and solids, with faster speeds in denser materials.
Sound Frequency Classification
- Low-frequency sounds are classified as bass, not treble, which refers to higher frequency sounds.
Measuring Sound Intensity
- The amplitude of a sound, which determines its loudness, is measured in decibels (dB).
Sound Production in Instruments
- The saxophone produces sound through the vibration of a reed, not a string, which is attached to a mouthpiece.
