The difference between high and low frequency sound waves lies in their respective rates of vibration or oscillation. Frequency is the measure of the number of complete oscillations or cycles of a wave that occur per unit of time, usually expressed in Hertz (Hz).
High frequency sound waves have a higher rate of oscillation, meaning they complete more cycles in a given time period. They have a higher pitch, which is associated with sounds that are perceived as "high" in frequency, such as a bird chirping or a whistle. High frequency waves typically have shorter wavelengths.
On the other hand, low frequency sound waves have a lower rate of oscillation and longer wavelengths. They are associated with sounds perceived as "low" in pitch, such as a deep rumble or a bass note.
When it comes to hearing sounds, the human auditory system is generally more sensitive to frequencies in the range of 20 Hz to 20,000 Hz, with the sensitivity peaking around 2,000 to 5,000 Hz. This range is often referred to as the audible frequency range. However, the specific sensitivity and range can vary between individuals.
In general, human hearing is most acute in the mid-frequency range, typically around 1,000 to 4,000 Hz. This is the range where our ears are most sensitive to detecting and perceiving sounds. Consequently, sounds within this frequency range are often considered more "audible" or "clear" to us.
However, it's important to note that different individuals may have variations in their hearing sensitivity across different frequencies. Factors such as age, exposure to loud noises, and individual variations can affect one's ability to perceive certain frequencies.
In summary, both high and low frequency sound waves contribute to our perception of the auditory world. However, the human auditory system is generally most sensitive to frequencies within the mid-range, around 1,000 to 4,000 Hz, which is why sounds within this range are often considered better for hearing and perceiving various auditory stimuli.
