Deafness genes A2/KCN24 and A9/COCH age and hearing impairment and language difference between the rate of correlation
8 (15.2); 180 patients (72oA) recorded in the ipsilateral and contralateral acoustic stapedius reflex (AR), 70 patients (28%) did not record to the AR; 161 cases (64.4%) to revive positive, 89 cases (35.6) to revive negative. Cause of 96 cases of infected persons,[link widoczny dla zalogowanych], tympanic pressure were 56 cases of figure-A, B-lO cases, C-3O cases; 66 patients with AR,[link widoczny dla zalogowanych], AR was not elicited by 3O cases, 66 cases to revive the positive and negative 3O cases; 55 cases of vasogenic cases, A type 44 cases, B in 4 cases, C-type in 7 cases, there AR44 cases, no AR11 cases, 44 cases to revive the positive and negative in 11 cases; 25 cases were all patients with drug A, were lured out of AR, to revive the positive 1O and negative in 15 cases of traumatic} 19 patients, A-type 19 cases, B-2 patients,[link widoczny dla zalogowanych], C in 1 case, there AR2O cases, no AR in 2 cases,[link widoczny dla zalogowanych], to revive the positive 12 cases, negative lO cases; literature, there is no allergic reaction caused by the AI of the test results ASND records of patients, this pressure in the tympanic cavity of 52 cases with 13 cases of figure A, B-39 cases, 13 cases with AR, no AR39 cases, 13 cases revive the positive and negative in 39 patients. Change should be derived 75% of patients with type B tympanogram pressure map, and revitalize the lead not AR-negative,[link widoczny dla zalogowanych], similar to secretory otitis media performance, but no middle ear disease and eustachian tube can not be improved by blowing Zhang desensitization AI index can return to normal, hearing improved significantly, probably by the cochlear patency disorders (caused by the antigen) caused by stapedius may also be the decreased excitability. Author believes that: AI test ANSD the differential diagnosis of various causes an important role, can be used for clinical audiological testing. (Lin Shangze Abstract) 361 noise with Finnish speech audiometry test assessment sensorineural hearing loss [English] / LaitakariK ... / / ScandAudio1. A 2001,30 (Suppl52). 165 ~ 166 for a modern society, in everyday speech in a noisy environment is a basic understanding of the skills. Have confirmed sensorineural hearing loss compared to patients with normal hearing ability decreased speech discrimination in noise. The purpose of this study is the observation of sensorineural hearing loss of varying degrees of noise in the threshold of speech recognition. Methods and materials: in 151 patients with varying degrees of sensorineural hearing loss patients (all backbone conduction threshold difference of 10dB or less), and 2O of normal hearing persons (all pure tone thresholds less than 20dBHL) pure tone audiometry, but also on which Subjects were 91 patients with a quiet environment, speech recognition threshold determination. Finnish computerized speech recognition threshold test noise is from the 510 pairs of syllables were randomly selected audiometry materials and in different signal to noise ratio and digital noise in mixed language, using headphones to send. After a short training, audiometry start. Start the loudness level of comfort from the strength of patient selection. Signal to noise ratio can identify some words from the beginning, then increase the signal to noise ratio by 2dB noise intensity as a file, a file of every four words decay, until all four word recognition errors, the SNR of the previous file initial signal to noise ratio. Noise in the speech recognition threshold is calculated from the initial signal to noise ratio in each of a word minus 0.5dB. Test computer connected to a standard clinical audiometer. Subjects were familiar with the test, the test time is about 1 to 2 minutes. Now repeat the experiment again. RESULTS: Pure tone audiometry PTA (0.5 ~ 4kHz) and the noise in the speech recognition threshold a Pearson correlation coefficient r 0.67 (P <O.001). Quiet environment, speech recognition test with the PTA of the correlation coefficient is r one by one 0.58 (P <O.001), and noise in the speech recognition threshold for a correlation coefficient of r = 0,58 (P <O.001). Noise in the speech recognition threshold and 0.5kHz, lkHz, 2kHz and 4kHz in the air conduction hearing threshold is the correlation coefficient of o. 45, o. 52, o. 66 and o. 63. Repeated measurements of noise in the individual differences in speech recognition threshold an average of 1.5dB (standard deviation of 1.5dB) is about the range of experimental variables may 5oA (12 ~ 20dB). Discussion: Because the needs of practice, the Finnish speech recognition in noise is to use words instead of the threshold test of the statement is obviously not as good as the accuracy test with audiometry income statement. This study also showed that even in a quiet environment within the results of speech audiometry, speech recognition threshold in noise and quiet environment, the relevance of speech recognition is still loose, suggesting that these two tests is to measure the different types of hearing impairment . Even the Finnish trial also showed that the higher speech frequencies (2kHz and 4kHz) speech recognition and noise in the Kan also has the best correlation, this test can be effectively
