The perceived frequency of a sound wave, often referred to as its pitch, is determined by the frequency of the sound wave itself, which is measured in hertz (Hz). Frequency indicates the number of cycles of the wave that occur in one second.
When sound waves have higher frequencies, they are perceived as higher pitches (like a whistle), while lower frequencies correspond to lower pitches (like a drum). Human hearing typically ranges from about 20 Hz to 20,000 Hz (20 kHz), although sensitivity can vary among individuals and tends to decline with age, especially for higher frequencies.
The perceived frequency can also be influenced by various factors, including:
- **Loudness**: Louder sounds can sometimes seem to have a higher pitch due to the way our ears and brain process sound.
- **Timbre**: The quality or color of a sound, which can affect how we perceive pitch.
- **Doppler Effect**: The change in perceived frequency when a sound source moves relative to an observer.
Overall, while the actual frequency of a sound wave is objective and measurable, the perceived frequency can be influenced by various subjective factors.
