Problems solved by technology

[0004] The survey found that subjectively, it is very easy for users to ignore the length of time the earphones are used and the volume of the earphones. Specifically, when users use earphones to listen to music, they often ignore the use time. In some cases, sometimes the earphones can be used for as long as 5 hours or more, and the volume of the earphones will be ignored when the earphones are used for a long time. For example, users often choose high volume when playing online games or listening to music. Damage to hearing caused by ignoring the hazards of high volume for a long time
[0005] The existing earphones on the market only have sound adjustment, but no hearing loss prevention function

Embodiment 1

[0036] Embodiment one: a kind of method that is applied to the prevention hearing loss of earphone, refer to figure 1 , including the following steps:

[0037] Step 11: Set the safe listening time δ, the safe listening time δ is the safe use time of the earphones, using the earphones for a continuous length of time to reach the safe listening time δ will not cause hearing damage; the safe listening time δ is voluntarily determined by the user Set, for example, when the user uses headphones, set the safe listening time δ to δ 1 , generally, the value range of the safe listening time δ is 100-200 minutes.

[0038] Step 12: When the time of using the earphone exceeds the safe listening time δ, the user is reminded through the earphone and the power of the earphone is cut off.

[0039] Step 13: Set the best listening loudness d; the best listening loudness d is set or preset by the user.

[0040] Step 14: When the loudness of the earphone is greater than the optimal listening l...

Embodiment 2

[0042] Embodiment two: a kind of method that is applied to the prevention hearing loss of earphone, refer to figure 1 and figure 2 , the difference from Example 1 is:

[0043] The setting safe listening time δ includes:

[0044] Step 111: Set different safe listening time δ according to different earphone types in advance.

[0045] Headphone types include earmuffs and earplugs. The distance from the sound outlet to the inner ear of the earplugs is smaller than that of the earmuffs. The safe listening time δ of the earmuffs is δ 1 , the safe listening time δ corresponding to earphones is δ 2 , corresponding to δ 1 greater than δ 2 .

[0046] Step 112: Determine the earphone type and select the corresponding safe listening time δ.

[0047] Select the safe listening time δ by the type of earphone. When the earphone is an earmuff, select δ for the safe listening time δ 1 , when the earphone is an earphone, the safe listening time δ selects δ 2 .

[0048]The method for p...

Embodiment 3

[0049] Embodiment three: a kind of device that is applied to earphone to prevent hearing damage, refer to image 3 , including a memory, a time counter, a distance detector and a memory, wherein the memory, the time counter and the distance detector are all connected to the processor, and the processor is connected to the earphone.

[0050] Among them, the memory is used to store the safe listening time δ, which is the safe use time of the earphones, and the continuous use of the earphones to reach the safe listening time δ will not cause hearing damage, and one or more pieces of reminder music are also stored in the memory , the reminder music is used to remind the user to take a break when listening to music with headphones for too long.

[0051] The time counter is used to count the time when the user uses the earphone to listen to the sound, that is, the time when the earphone is working.

[0052] Distance detector. The distance detector is an infrared sensor installed in...

Abstract

The invention discloses a method and a device for preventing hearing damage applied to an earphone, and belongs to the technical field of hearing protection, and the method comprises the steps: setting a safe listening time which is the safe use time of the earphone, and enabling the continuous duration of using the earphone to reach the safe listening time without causing hearing damage; and whenthe time of using the earphone exceeds the safe listening time, reminding a user through the earphone and cutting off the earphone power supply. By timing the use duration of the earphone, when the use duration of the earphone exceeds the set safe listening time, the earphone reminds an earphone user to remind the user to have a rest, and hearing damage caused by too long ear use time due to thefact that the use duration of the earphone is ignored when the user uses the earphone is avoided.

Description

technical field [0001] The invention relates to the technical field of hearing protection, in particular to a method and device for preventing hearing damage. Background technique [0002] The irreversible damage to hearing caused by noise is called permanent hearing threshold shift (noise-induced permanent threshold shift, NIPTS or PTS), also called permanent hearing loss. Temporary threshold shift (noise-induced temporary threshold shift, NITTS or TTS), also known as temporary hearing loss. PTS caused by industrial noise is mostly developed from TTS, and there is a slow development process, forming a V-shaped or U-shaped hearing loss at 3000-6000 Hz on the audiogram, which is the so-called 4000 Hz listening valley (dip). High-frequency "hearing valley" is a typical feature of occupational noise-induced hearing loss, and it is also the early signal of noise deafness. [0003] The current teenagers use earphones more and more frequently, and using earphones too frequently ...
