Problems solved by technology

[0005] Secondly, in addition to dealing with professional acoustic measuring instruments, some mobile phones currently on the market have begun to analyze people's listening data, but because people use different types of headphones, different brands, and different scenarios, it is difficult to do it on mobile phones. Accurate sound pressure level calculation

Abstract

The invention is suitable for the technical field of earphones, and provides a method and a device for acquiring the sound pressure level of an earphone, and the earphone. The method comprises the following steps: acquiring an audio digital signal input into the earphone; according to a frequency response curve of the earphone, performing frequency response weighting processing on the audio digital signal to obtain an original sound pressure level of the audio digital signal after passing through the earphone; and performing frequency weighting on the original sound pressure level to obtain the hearing sound pressure level of the earphone. According to the invention, the frequency response weighting processing is carried out on the audio digital signal according to the frequency response of the earphone, the original sound pressure level of the audio digital signal after passing through the earphone is obtained, the hearing sound pressure level of the earphone is obtained after the frequency weighting is carried out on the original sound pressure level, and the frequency weighting simulates the response of human ears to pure tones with different loudnesses. The finally obtained sound pressure level is closer to the real feeling of human ears, and hearing protection of a user is facilitated.

Description

technical field [0001] The present application belongs to the technical field of earphones, and in particular relates to a method and device for obtaining the sound pressure level of earphones and earphones. Background technique [0002] At present, the number of people wearing headphones is increasing, and there are more and more usage scenarios. Some children have begun to use headphones in their study and life. However, most people usually do not have the concept of hearing protection. In order to hear more clearly and cover the surrounding noise, etc., the volume of the earphones is turned up, which makes the sound field output of the earphones too strong, and long-term use is likely to cause hearing loss. [0003] Since many people's ears are not very sensitive to sound, they cannot judge the sound pressure level subjectively during the listening process. Even people with sensitive ears may not be able to accurately judge whether the volume is too loud after their ears...
