[0060] 参阅图2,为本发明实施例中的一种多功能听力计的一个实施例结构示意图,其中,听力计包括控制器1、启动模块2、查询模块3和驱动电路4 ;控制器1用于控制听力计的运行;启动模块2用于根据预设的规则,启动相对应的查询模块3 ;查询模块3用于提供听力计检测功能;控制器1通过驱动电路4分别与启动模块2、查询模块3连接。 A controller; [0060] Referring to Figure 2, one embodiment of a multifunctional audiometer schematic structural embodiment, wherein the audiometric includes a controller 1, start module 2, the query module 3 and the drive circuit 4 embodiment of the present invention 1 for controlling the operation of the audiometer; starting module 2 according to a preset rule, the query module corresponding starting 3; 3 query module for providing an audiometer detection; controller 1 through the driving circuit 4, respectively activation module 2, the query module 3 is connected. 根据一定的规则,控制器1通过驱动电路4,通过启动模块2,启动相应的查询模块3,根据相应查询模块3反馈回来的参数,控制器1发出相应的控制信号,从而驱动相应的检测电路进行检测,获得检测结果。 According to certain rules, the controller 1 through the drive circuit 4, by activating the module 2, module 3 starts the appropriate query, query module 3 according to the corresponding parameters fed back, the controller 1 issues a corresponding control signal to drive a corresponding detection circuit testing, obtaining test results.

[0061] 参阅图3,查询模块3包括音频检测单元31、语言听力检测单元32、特殊检测单元33 ;其中,音频检测单元31针对气导耳机和骨导耳机,提供包括左耳刺激声与右耳掩蔽噪声或左耳掩蔽噪声与右耳刺激声,其中刺激声包括纯音、啭音,噪声包括窄带噪声、白噪声;语言听力检测单元32提供包括单耳语音信号、单耳语音信号与对侧掩蔽噪声、单耳混合输入信号、双耳输入不同语音信号、双耳掩蔽噪声,其中语音信号可以是麦克风(MIC)、磁带机(CD),噪声包括窄带噪声、白噪声;特殊检测单元33用于提供SISI检测、ABLE检测、STENGER检测、HIS检测,其中的SISI检测称为短增量敏感指数试验,用于检查听觉对声音强度微量改变的察觉能力,用1000Hz的纯音,强度为阈上20dB,应用调幅装置使声强每5秒出现一次短时程的ldB增量(上升及下降时间各为50ms、持续200ms),受检者 [0061] Referring to Figure 3, the query module 3 includes an audio detection unit 31, speech and hearing detection unit 32, a special detection unit 33; wherein the audio detection unit 31 for air conduction and bone conduction headset headset, providing a left and a right sound stimulation masking noise ear or left ear and right ear noise masking stimulus, which comprises a pure tone stimulus, warble tones, narrowband noise including noise, white noise; language hearing detecting unit 32 includes a monaural voice signal, a monaural speech signal from the opposite side masking noise, a monaural input signal is mixed, different binaural input speech signal, binaural masking noise, wherein the speech signal may be a microphone (the mIC), the drive (CD), a narrowband noise including noise, white noise; detecting unit 33 with a special to provide detection SISI, ABLE detection, detection STENGER, HIS is detected, wherein the detection is called SISI short increment sensitivity index test, checking for the ability to detect trace auditory sound intensity changes, pure tone of 1000Hz, the intensity threshold 20dB application means that the AM sound intensity of a short duration ldB increase (rise and fall times each 50ms, continuous 200ms) occurs every 5 seconds, the subject 共听20次增幅音,每听到1次,得分5%,总分在30%以下为正常,35〜65%为可疑,70%以上者为重振试验阳性,提示耳蜗病变的存在。 A total of 20 times to listen to the sound growth, hear every 1, 5% score, score 30% or less as normal, 35~65% as suspicious, more than 70% of those who test positive for the revitalization, suggesting the presence of cochlear lesions.

[0062] ABLE检测称为双耳交替响度平衡试验,是检查有无响度重振的常用方法,适合于双耳听力相差20〜50dB(HL)的患者。 [0062] ABLE detection is called alternate binaural loudness balance test, a common method is to check for a revitalized loudness, the phase difference is adapted to binaural hearing 20~50dB (HL) patients. 当用低强度音刺激时,一耳较另一耳听力差,但高强度音刺激时,两耳对同一频率的音调所感受的响度可能相等,甚至差耳反而敏感,这种患侧强度增加较健侧为快的现象,称重振现象(recruitment phenomenon)。 When using low-intensity sound stimulus, a difference between the ear than the other ear hearing, but at high intensity sound stimulus, the ears of the same frequency tones perceived loudness may be equal, but even the worse ear sensitive, this increase in strength ipsilateral faster than the healthy side of the phenomenon, called to revive the phenomenon (recruitment phenomenon). 耳蜗病变引起的感音性聋常有响度重振。 Sensorineural deafness caused by cochlear lesions often loudness revive. 例如病人的右耳听阈为OdB,左耳听阈为40dB。 For example, the patient's right ear hearing thresholds as OdB, left ear hearing threshold is 40dB. 当右耳声强级增加20dB时,左耳只须从其听阈(40dB)增加10dB就感到两耳听到的响度相等,此即表示有响度重振,提示存在耳蜗病变。 When the right ear sound intensity level increase of 20dB, only the left ear from hearing threshold (40dB) 10dB increase felt equal loudness ears to hear, namely expressed Loudness Recruitment, suggesting the presence of cochlear lesions. 检查方法为先测定患者两耳纯音听阈,选用两耳听力相差20dB以上的频率,每10〜20dB —档地增加一耳的声强度,并逐档调节另一耳的声强度至两耳感到的响度相同时为止。 The method of checking for the first patient ears measured pure tone hearing threshold, 20dB or more selected frequency difference hearing ears, each 10~20dB - increase the acoustic intensity profile of an ear, and by adjusting the acoustic intensity profile to the other ear of the ears was loudness up at the same time.

[0063] STENGER检测称为伪聋即装聋,是指听觉系统无明显器质性病变,听力正常,耳自称耳聋。 [0063] STENGER called false detection deaf deaf i.e., no auditory system refers to organic disease, normal hearing ear deafness claimed. 伪聋者并无神经心理创伤,往往带有目的或企图进行伪装,主观表现非常严重,通过多次的听力学检测以及客观听力检查有助于鉴别。 Pseudo-deaf not nerve trauma, often with the purpose or attempt to disguise, subjective performance is very serious, many times by audiological testing and objective hearing tests help to identify. 检查方法是同时想两耳发送同一频率纯音信号,对于听力较好的耳,声强度可以设置阀值高于10dB,对于较差的耳可以设置阀值低于10dBo Check method is to transmit the same frequency like the ears pure tone signal, for better hearing ear, the sound intensity may be higher than the set threshold 10dB, for the poor ear is below a threshold may be provided 10dBo
