Speech Recognition Threshold SRT: This exam sought confirmation of air conduction thresholds.
In the PTA air conduction, thresholds were investigated in the frequencies of 500, 1000, 2000 and 4000 Hz.
The degree of hearing loss was classified by analyzing the mean of air conduction thresholds at frequencies of 500, 1000 and 2000 Hz.
The bone conduction thresholds were obtained at 500, 1000, 2000, 3000 and 4000 Hz, using the same procedure described for the AC.
The degree of hearing loss was classified according to Lloyd and Kaplan,analyzing the average air conduction thresholds in the frequencies of 500, 1,000 and 2,000 Hz.
The air conduction thresholds for the right and left ears were tested, in the frequencies of 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18 kHz.
The hearing loss levels were determined by taking the average of pure tone air conduction thresholds, determined at 0.5, 1, 2, and 4 kHz, in accordance with the intervals given in Table 1.
When bone or air conduction thresholds could not be measured in a certain frequency it was registered as non-measurable; a value of 10dB above the device's capacity was considered the threshold. .
A number of studies have used plastic tubes inserted into the external auditory canal andreport a 15 to 30 dB improvement in air conduction thresholds, especially at a frequency of 4 kHz.
One belated investigation of air and bone conduction thresholds has observed middle-ear losses of as much as 12 dB in elderly patients.
After the patient's exams were analyzed, she has been indicated to use BAHA Cochlear Divine on her left ear,which is the ear with best bone conduction thresholds and the side preferred by the patient during the external test.
Pure-tone audiometry for air conduction thresholds at 500, 1000 and 2000Hz is traditionally used to classify the degree of hearing loss in each ear.
The standard and most common type of hearing testis pure tone audiometry, which measures the air and bone conduction thresholds for each ear in a set of 8 standard frequencies from 250Hz to 8000Hz.
Left ears presented air conduction thresholds at high frequencies higher than right ears, and this finding was also reported in another study for frequencies of 9 kHz and 11.2 kHz.
Hearing thresholds with air conduction were obtained at frequencies ranging from 250-8,000 Hz andwith bone conduction at frequencies from 500-4,000 Hz whenever air conduction thresholds exceeded 15 dB HL.
In this case, the pure tone audiometry will show air conduction thresholds above 15 dB and bone conduction thresholds within the standards of normality.
The bone conduction thresholds for the frequencies of 2,000; 3,000 and 4,000 Hz, were obtained in two different situations: open EEC and closed EEC the patient occluded the ear canal with his own index finger.
The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds.
In the threshold tonal audiometry, carried out in a sound-treated booth, we assessed the frequencies from 250 to 8,000 Hz through air conduction; and500 to 4,000 Hz through bone conduction in the frequencies with air conduction thresholds above 20 dB HL.
We also assessed tonal conduction thresholds in the frequencies of 0.25; 0.5; 1; 2; 4; 6 and 8 KHz and in the bone pathway in the frequencies of 0.5; 1; 2 and 4 KHz before surgery.
In Brazil, the classification proposed by Lloyd& Kaplan is the most widely used scheme to assess the degree of hearing loss in adult subjects.Normal hearing in this classification is assigned to subjects whose mean air conduction thresholds at 500, 1000 and 2000 Hz is of 25 dBNA and under.
The MHL is diagnosed when the bone conduction thresholds are greater than 15 dBHL and air conduction thresholds greater than 25 dB, with air-bone gap greater than or equal to 15, in, at least, one frequency.
After the otorhinolaryngological examination, the immitancemetric evaluations were conducted and tests which are appropriate for the patients' ages, physical and mental efficiencies, andboth air and bone conduction thresholds were determined at 250, 500, 1000, 2000, 4000, 6000, and 8000 Hz.
All the participants who had a gap between the air and bone conduction thresholds in the frequencies of 2,000;3,000 and 4,000 Hz, had the bone conduction thresholds reassessed with the occlusion of the external ear canal under test with the patient's own index finger.
Since the average mid-frequency hearing loss in the Hultcrantz et al. study had a mean of 18.8 dB,a degree of hearing loss, not detected by the routine 20 dB pure-tone hearing screening, is important to obtain air and bone conduction thresholds for any child suspected of having TS.
The SSI sentences were applied in both groups with an intensity of 40dBSL,based on the pure tone air conduction thresholds in the frequencies of 500, 1000 and 2000Hz; the competitive message intensity varied according to the required in each test condition.
The Optimized Method, which is similar to the Plateau, however faster and of easier applicability, for using a smaller number of masking increments in obtaining the hearing threshold, is based on air conduction thresholds AC in the tested ear TE to calculate the initial masking level.
The normal hearing was considered when the air conduction thresholds were lower than 20 dB HL in the frequencies of 250 kHz to 8 kHz and type A tympanogram contralateral acoustic reflex present bilaterally; while in Speech Audiometry, a speech recognition threshold SRT equal to or lower than 20 dB HL and Word Recognition Score WR of 92% or more, bilaterally.
The conventional PTA assessed air-conduction hearing thresholds at frequencies from 250 Hz to 8000 Hz and bone conduction hearing thresholds, when the air conduction thresholds showed values>25 dB HL for frequencies from 500 Hz to 4000 Hz.
Table 1 shows the mean values for pre and postoperative air and bone conduction thresholds, air-bone gap, and SRI speech recognition index. The first data set belongs to patients using Teflon implants group I, while Table 2 presents the data for patients using mixed Teflon and metal implants group II. There was statistically significant threshold improvement for all frequencies in air conduction, except 8kHz Fig.
