The Difference Between High-frequency Sound and Low-frequency Sound

Both high-frequency sound and low-frequency sound have their own characteristics and effects. Let's take a look:

High-frequency sound refers to high-frequency sound, generally refers to sound at 5000 Hz or higher. High-frequency sounds, such as knife shearing, screaming, whistle sound, etc., have high frequency and small sound wave amplitude. Compared with other sounds, these sounds attract people's attention more. High-frequency sound can bring clarity and detail when listening, so in some audio fields, such as recording, music, etc., many people like the performance of high-frequency sound.

High-frequency sound also has its negative effects. Frequent listening to high-frequency sound can cause damage to the ears.
Low-frequency sound refers to low frequency, long wavelength, and loud sound, generally in the range of 20 Hz to 500 Hz. Common low-frequency sounds include low bass, artillery shells, explosions, etc. Low-frequency sound can bring people a sense of background and heaviness, which is suitable for creating a magnificent atmosphere. Low-frequency sound also helps to relieve fatigue, enhance physical sensation, increase blood flow and other positive effects.

Prolonged exposure to high-volume, low-frequency sounds can affect the human cardiovascular system, such as increasing heart rate and blood pressure.

High-frequency sounds are fundamentally different from low-frequency sounds. First, the frequency of the sound. High-frequency sounds have high frequencies, while low-frequency sounds have low frequencies. Second, the energy distribution in the sound. The energy of high-frequency sounds is distributed in the high-frequency area, while the energy of low-frequency sounds is distributed in the low-frequency area. Finally, the impact on the human body. High-frequency sounds can stimulate alertness, while low-frequency sounds can bring people a sense of tranquility and depth.
