The effects of sounds that cannot be heard by the ears.
Introducing the effects of "low-frequency sounds" that exist as a matter of course in our daily lives!
This blog focuses on "low-frequency sound," which is a type of sound that is difficult for the human ear to hear, even though it is still a sound. Low frequency refers to sounds with a frequency of 100 Hz or lower, and sound is a vibration that is transmitted through gases, liquids, and solids. The number of vibrations per second is referred to as frequency. Generally, sounds with a frequency below 100 Hz are called low-frequency sounds, and among them, sounds below 20 Hz that are difficult for humans to hear are referred to as infrasound. "Low-frequency sound" is commonly present in our daily lives. It is primarily generated by large structures, machinery, and facilities. *For more details about the blog, you can view the related links. *For more information, please refer to the PDF materials or feel free to contact us.
