Abstract
Description
Technical Field
[0001] This invention relates to the field of hearing aids, specifically to a hearing aid method and device based on Bluetooth dual-mode audio functionality. Background Technology
[0002] Bluetooth hearing aids are a modern hearing aid device that integrates Bluetooth technology, making them not only hearing aids but also personal audio centers. Bluetooth hearing aids can connect directly to mobile phones via Bluetooth, allowing users to answer calls, receive audio messages, make voice and video calls, and listen to music and videos directly from their phones. While driving, users can use Bluetooth hearing aids to listen to radio and music from their car's in-car player, providing a more convenient entertainment experience. Chinese Patent Publication No. CN113507678B discloses a Bluetooth answering method and device for a hearing aid, applied to a Bluetooth answering scenario for a hearing aid. The method includes: connecting the hearing aid to a terminal device via Bluetooth; determining whether there is interfering sound in the answering scenario that requires switching Bluetooth modes; when there is interfering sound in the answering scenario, determining the loudness of the interfering sound to decide whether to switch Bluetooth modes. While accessing Bluetooth mode, this hearing aid method retains the sound access function of the answering scenario, and can reasonably determine whether to play the sound of the answering scenario based on the loudness of external sounds. Furthermore, hearing-impaired patients can effectively control the limitations of sound playback within the answering scenario by adjusting the volume of the Bluetooth mode, achieving a similar answering mechanism to the human ear. When determining whether to play the sound of the answering scenario, it can also automatically filter noise based on preset sound spectrum information. The aforementioned technology automatically limits the loudness of sounds within the listening environment when external sounds exceed a safe range. This is only applicable to Bluetooth listening scenarios and not to entertainment scenarios such as music or radio broadcasts. Forcibly connecting hearing aids to smart devices via Bluetooth can affect the user's interaction with people or things in the surrounding environment. This severely limits the application of Bluetooth technology in the field of hearing aids. Users are forced to rely on conventional hearing aid methods to listen to music or radio broadcasts, which not only fails to reduce the operating burden of the hearing aids, but also makes the hearing effect entirely dependent on the performance of the hearing aids. Therefore, there is an urgent need for a hearing aid method and device based on Bluetooth dual-mode audio functionality.

[0013] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this disclosure. Attached Figure Description

Detailed Implementation
[0016] The embodiments of the technical solution of this invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of this invention and are therefore intended to limit the scope of protection of this invention.
[0017] Figure 1This invention provides a flowchart of a hearing aid method based on Bluetooth dual-mode audio functionality. The method is applied to a binaural hearing aid terminal, which can display images, videos, text messages, WeChat messages, and other information. The terminal can be equipped with any terminal device with a display screen, such as a mobile phone, computer, digital broadcasting terminal, messaging device, game console, tablet, medical device, fitness equipment, or personal digital assistant. This embodiment provides a hearing aid method based on Bluetooth dual-mode audio functionality, such as... Figure 1 As shown, the method, applied to digital hearing aids, wherein the Bluetooth dual-mode audio function can simultaneously support audio transmission and data communication, includes the following steps S10-S30: In step S10, the digital hearing aid is connected via Bluetooth to at least one external audio device, the external audio device comprising at least one audio software. In this implementation, Bluetooth pairing first requires ensuring that both the hearing aid and the external audio device have Bluetooth functionality and support the same Bluetooth version or protocol. After turning on the hearing aid's Bluetooth function and setting it to discoverable mode, the external audio device searches for available Bluetooth devices and selects to pair with the hearing aid. Once paired successfully, the external audio device can transmit audio signals to the hearing aid via Bluetooth. The transmitted audio signals may include music, call sounds, podcasts, audiobooks, etc. The external audio device can be a mobile phone, computer, speaker, etc., and the audio software may include music players, video players, phone applications, etc.
[0018] In step S20, the digital hearing aid acquires the sound signal transmitted via Bluetooth from the external audio device and processes the sound signal into a Bluetooth output signal. In step S30, the digital hearing aid collects sound signals from the external environment other than the external audio signal and noise signal, and processes the sound signal into an environmental output signal; In this implementation, the external audio device can also privately play the same audio content inside the digital hearing aid while playing external sounds normally, without affecting the auditory experience of people around the hearing-impaired patient. On the other hand, the external audio device directly transmits audio information to the digital hearing aid, avoiding the performance defects in the process of the digital hearing aid collecting audio information.
[0019] In step S40, the Bluetooth output signal and the environmental output signal are integrated and output so that the hearing-impaired patient can hear the complete sound signal except for the noise signal. In this implementation, the integrated output can be integrated using Fourier transform. Fourier transform integration refers to merging or integrating multiple signals in the frequency domain after processing them through Fourier transform, and then converting them back to the time domain through inverse Fourier transform for playback by the speaker. Alternatively, two speakers can be used to output the Bluetooth signal and the ambient signal respectively, so that the sound generated by the Bluetooth signal and the sound generated by the ambient signal interfere and mix in the ear canal, achieving the same effect.
[0020] In one embodiment, such as Figure 2 As shown, in step S20, the digital hearing aid acquires the sound signal transmitted via Bluetooth from the external audio device and processes the sound signal into a Bluetooth output signal, including the following steps S21-S23: In step S21, the digital hearing aid receives Bluetooth audio information transmitted by an external audio device, the Bluetooth audio information consisting of Bluetooth audio signal and Bluetooth audio loudness information; In step S22, the Bluetooth audio signal is adjusted according to the Bluetooth audio loudness information to obtain an analog audio signal that the external audio device plays Bluetooth audio signals in the external environment. In this implementation, the Bluetooth audio loudness information is set by the operator of the external audio device. If the volume of the external audio device increases, the loudness of the Bluetooth audio signal also needs to be amplified accordingly. If the volume of the external audio device decreases, the loudness of the Bluetooth audio signal also needs to be reduced accordingly. For example, in a car Bluetooth connection scenario, if the user increases the volume of the car's music, the sound of the car's music in the private hearing environment of the hearing-impaired patient will also be amplified synchronously. The hearing-impaired patient and the people around them can hear the same sound, which enhances the interaction ability between the hearing-impaired patient and the people around them.
[0021] In step S23, the sound signals in different frequency domains within the analog audio signal are differentiated to obtain a Bluetooth output signal that conforms to the hearing loss mechanism of hearing-impaired patients. In this implementation, the differential processing involves multi-channel filtering and differential amplification. Multi-channel filtering can be achieved using multiple filters with different frequency domains, resulting in multiple pure tone signals that are complementary to the ambient sound signal. Differential amplification can be achieved using multiple amplifiers, which can amplify different pure tone signals by different factors. By enhancing sound signals at certain frequencies, sound signals at other frequencies are suppressed or reduced to compensate for the hearing loss of hearing-impaired patients.
[0022] In one embodiment, such as Figure 3 As shown, in step S30, the digital hearing aid acquires sound signals from the external environment other than amplified audio signals and noise signals, and processes these sound signals into an environmental output signal, including the following steps S31-S33: In step S31, the digital hearing aid receives a complete sound signal from the external environment, which includes an ambient sound signal, an external audio signal, and a noise signal. In step S32, the noise signal and the external audio signal in the complete sound signal are removed in sequence to obtain the ambient sound signal; In this implementation, the process involves noise filtering and specific filtering. Noise filtering can be implemented using filters to remove sound signals that are inaudible to the human ear and that may interfere with speech. Specific filtering can employ Fourier transform filtering, a signal processing technique performed in the frequency domain. It uses Fourier transform to convert the signal from the time domain to the frequency domain, then filters the signal in the frequency domain, and finally uses inverse Fourier transform to convert the filtered signal back to the time domain. Given the known Bluetooth audio signal, and since the external speaker audio signal is essentially the same as the Bluetooth audio signal, this method can be used to remove external speaker audio signals from the external environment that are essentially the same as the Bluetooth audio signal, thus avoiding interference with the Bluetooth audio signal output and ensuring the integrity and intelligibility of the audio information. In step S33, the sounds in different frequency domains within the ambient sound signal are differentiated to obtain an environmental output signal that conforms to the hearing loss mechanism of hearing-impaired patients. In this implementation, the differentiation process consists of multi-channel filtering and differential amplification. Multi-channel filtering can be achieved using multiple filters with different frequency domains, resulting in multiple pure tone signals that are complementary to the ambient sound signal. Differential amplification can be achieved using multiple amplifiers, which can amplify different pure tone signals by different factors. For example, if a hearing-impaired patient has more severe hearing loss in the high-frequency region, the system will correspondingly amplify the sound at these frequencies so that the user can hear better.
[0023] The following are embodiments of the apparatus disclosed herein, which can be used to execute embodiments of the method disclosed herein.

[0025] This disclosure, by collecting sound signals from the external environment other than amplified audio signals and noise signals, and synthesizing these sound signals with the sound signals transmitted via Bluetooth from the amplified audio device, can obtain integrated output information whose components are indistinguishable from the sound signals in the external environment. On the one hand, the amplified audio device can also privately play the same audio content within the digital hearing aid while playing external sounds normally, without affecting the auditory experience of people around the hearing-impaired patient.
