Background

Noise refers to sounds that vary in pitch and tone intensity in a chaotic and discordant manner. The sound generator is generated by irregular vibration of the sounding body, and the noise is generated when the sounding body vibrates irregularly from the physical point of view. From the viewpoint of environmental protection, all the sounds which obstruct normal rest, study and work of people and interfere with the sounds to be heard by people belong to noises. Noise is a type of sound that causes irritation or is too loud and harmful to human health. Health and safety conscious individuals have long recognized the need to adequately protect hearing in high noise environments, and much effort has been made to provide such protection. However, most experts in this field acknowledge that these efforts have not been completely successful.

In some computer rooms in hospital now, whether need personnel often to patrol the machine and operate normally, just need the staff closely work in high noise environment, present staff is mainly to block up the duct by taking cotton ball or sponge, therefore the hearing protection device of current use is uncomfortable usually to can not use in a flexible way, and give sound insulation effect is relatively poor, wears for a long time and can cause harm ears such as tinnitus. In addition, since human ear canals vary in size from a "small" canal with a diameter of 7mm to 8mm to a "medium" canal with a diameter of 9mm to 10mm and a "large" canal with a diameter of 11mm to 12mm and even as large as 14mm, earplugs of a single size cannot accommodate ear canals of different sizes and are inconvenient to clean.
