Problems solved by technology

However, patients often hang or suck the voice processor vertically on the mastoid bone of their head during actual use, so the difference in this configuration may lead to differences between the experimental results and the real results
[0006] Other testing equipment is equipment independently developed by some hearing companies or equipment improved from air conduction hearing aid testing equipment. The equipment independently developed by the company i

Embodiment 1

[0025] Embodiment 1: refer to Figure 1-6 . A hearing aid sound collection and analysis system, comprising a hearing aid 10, a magnetic implant 20 implanted under the outer skin 80 of a human skull 70, a sound collection device 30, and a processing and analysis system 40. The hearing aid 10 is connected by the sound collection device 30 and the magnetic implant The body 20 is connected, the hearing aid 10 is equipped with an electromagnetic bone conduction vibrator 25, and the lower side of the hearing aid 10 is provided with a magnetic gasket 50, the electromagnetic bone conduction vibrator 25 is connected with the outer magnetic gasket 50 of the hearing aid 10, and the sound collection device 30 includes a housing 33. Acoustic sensor 257. The housing 33 has a built-in acoustic sensor 257, and the acoustic sensor 257 can be oval, rectangular, square or other shapes with a thickness of 0.2 mm to 0.8 mm. The acoustic sensor 257 is connected with the processing and analysis syst...

Embodiment 2

[0031] Embodiment 2: refer to figure 1 . The processing and analysis system 40 includes an A / D converter 320, a data processing and analysis module 310, and the electrical sound signal sensed by the sound sensor 257 is input to the data processing and analysis module after the analog-to-digital conversion by the A / D converter 320 310. An amplifier 330 is connected between the sound sensor 257 and the data acquisition card 320. According to the signal strength sent by the sensor 257, the system 350 may increase the amplifier 330 as required. The received electrical sound signal is amplified by the amplifier 330 and then input to the A / D converter 320 , and then input to the data processing and analysis module 310 after being analog-to-digital converted by the A / D converter 320 .

[0032] The processing and analysis system 40 also includes a D / A converter 340, the hearing aid 10 is provided with a programming interface 125, and the signal output by the data processing and anal...

Abstract

The invention relates to a sound acquisition and analysis system for a hearing aid. The sound acquisition and analysis system for the hearing aid comprises a hearing aid, a magnetic implant, sound acquisition equipment and a processing and analysis system; the magnetic implant is implanted in the skin outside a human skull; the hearing aid is connected with the magnetic implant through the sound acquisition equipment; an electromagnetic bone conduction oscillator is arranged in the hearing aid; a magnetic gasket is arranged at the lower side of the hearing aid; the electromagnetic bone conduction oscillator is connected with the magnetic gasket outside the hearing aid through a conduction metal sheet; the sound acquisition equipment comprises a shell; a sound sensor is built in the shell; the sound sensor is in communication connection with the processing and analysis system; an upper magnetic end magnetically connected with the magnetic gasket is arranged at the upper end of the shell; and a lower magnetic end magnetically connected with the magnetic gasket is arranged at the lower end of the shell. By means of the sound acquisition and analysis system for the hearing aid disclosed by the invention, the sound acquisition equipment acquires sound transmitted through the magnetic gasket from the hearing aid, and converts the sound into electric signals; therefore, the output condition of the bone conduction hearing aid is measured in real time; the signals are output into the processing and analysis system, so that real-time processing and analysis are carried out; and thus, sound signals transmitting into the skull of a patient are evaluated.

Description

technical field [0001] The invention relates to a sound collection and analysis system, in particular to a hearing aid sound collection and analysis system. Background technique [0002] A bone-anchored hearing aid is a hearing aid based on bone conduction theory, including an implant implanted in the human body and a speech processor outside the body. Bone-anchor hearing aids use the human skull as a pathway for sound transmission into the inner ear. For patients with conductive deafness, bone-anchor hearing aids bypass the patient's outer and middle ears and transmit sound directly to the patient's normal cochlea through metal implants; For patients with unilateral deafness, bone-anchored hearing aids transmit sound through the skull from the deaf layer of the patient to the normal side. Most bone-anchor hearing aids require a titanium rod or plate to be surgically implanted into the skull, and a small joint is exposed to the patient's skin. The voice processor of the bon...
