Problems solved by technology

However, hearing damage can also occur if the user unintentionally raises the volume
In addition, the existing technology can also issue simple reminders through the app, but this method is difficult to become an effective measure and cannot really achieve the purpose of avoiding hearing damage

Embodiment Construction

[0019] The present invention will be described in more detail below in conjunction with the accompanying drawings and embodiments.

[0020] The invention discloses a hearing-protecting audio device output energy control method, please refer to figure 1 ,include:

[0021] Step S1, obtain the energy or pressure at the speaker or at any point in the sound field from the speaker to the tympanic membrane by calculation or measurement, and use it as the energy or pressure at the user's tympanic membrane or cochlea after compensation or calculation; specifically, the energy or pressure is not limited to Sound pressure, sound pressure level, sound power, sound intensity or sound intensity level, etc.

[0022] Step S2, calculate the cumulative hearing loss value based on the energy or pressure at the user's tympanic membrane or cochlea, or calculate the cumulative energy at any point in the sound field from the speaker to the tympanic membrane, and then calculate equivalently to the u...

Abstract

The invention discloses an audio device output energy control method capable of protecting hearing, and the method comprises the following steps: S1, obtaining energy or pressure intensity at a loudspeaker or at any point in a sound field from the loudspeaker to a tympanic membrane through a calculation or measurement mode, and compensating or calculating the energy or pressure intensity as energy or pressure intensity at the tympanic membrane or cochlea of a user; S2, calculating an accumulated hearing loss value according to the energy or pressure intensity of the tympanic membrane or cochlea of the user, or calculating the accumulated energy of the position according to the energy or pressure intensity of any point in the sound field from the loudspeaker to the tympanic membrane, and then equivalently calculating the accumulated hearing loss value of the tympanic membrane or cochlea of the user; S3, comparing the accumulated hearing loss value with a preset hearing loss threshold value, and if the accumulated hearing loss value reaches the hearing loss threshold value, executing the step S4; S4, reducing the volume of the audio device. According to the invention, energy at the tympanic membrane or cochlea of a user can be monitored in real time and output energy of the audio device can be adjusted in time, thereby realizing hearing protection.

Description

technical field [0001] The invention relates to an audio device output energy control method, in particular to an audio device output energy control method capable of protecting hearing. Background technique [0002] With the increasing frequency of people using audio devices such as earphones, hearing protection has become a very important thing. In many cases, when people realize that they need to protect their hearing, it is often when they find that there is a hearing problem. However, most cases of hearing loss are largely irreversible. For young people who often wear headphones, noise is the most serious cause of hearing loss. According to existing statistics, iPhone 6 in-ear headphones play for 8 hours at a volume of 5-6 bars or for 1 hour at a volume of 7-8 bars. Once the hearing threshold is exceeded, it will cause temporary hearing loss, and long-term exposure will cause irreversible hearing loss. [0003] In order to solve the problem of hearing loss, the existi...
