The masking level was increased in 10 dB and the threshold retested.
Table 2 shows the association between age and the result of the Masking Level Difference.
The masking level was increased in an amount equal to the variance of the threshold and retested.
When this happens it is recommended to consider small increases in the masking level to identify the plateau7-8.
Regarding gender and the result of the Masking Level Difference, another comparative study also found no significant difference between these two variable.
Table 4 shows the degree of speech intelligibility and the corresponding result of the Masking Level Difference test.
There was a high prevalence of altered Masking Level Difference results in the study sample: 34 subjects 59.7.
No studies were found relating the degree of speech intelligibility to the result of the Masking Level Difference test.
When the masking level was increased twice interval of 20dB with no changes to the threshold, the real hearing threshold was obtained.
Our sample did not indicate that there was a significant relationship between the ages of the subjects and the result of the Masking Level Difference test.
The initial masking level is generally bigger than the AC threshold for the NTE, enough to change the threshold and reach the plateau region7-8.
For the Optimized method, it was considered real threshold when this reached the plateau region,with the application of the expected masking level.
This can happen because the Optimized Method specifies a large increase in the masking level which can produce a masking level over 80 dB HL.
The Masking Level Difference was considered normal when the threshold difference between the signal/noise was greater than or equal to 9dB value used in normal clinical practice.
Among the behavioural tests that are part of auditory processing evaluation,the Masking Level Difference test is specifically directed towards investigating binaural³ interaction.
The inclusion criteria for the sample consisted of subjects who had undergone a tympanometry exam with tympanometric curve type A Jerger and Masking Level Difference assessment.
For Tinnitus Handicap Inventory and Minimum Masking Level, the 110 patients were separated into three groups with tinnitus, Pure Tone, Noise and multiple.
The relationship between the results of the contralateral andipsilateral acoustic reflex in both ears with the result of the Masking Level Difference test is presented in Tables 5 and.
Relationship between masking level difference test and acoustic reflex findings in children with phonological disorder is the thirteenth contribution from Bartz, Ribas, Machado, Ferreira, Laux and Peruch.
Psychoacoustic tests have been employed since the 40s4 and the four most used ones are: Pitch Match PM, Loudness Match LM,Minimum masking level MML and Residual Inhibition, RI.
From this study we conclude that there is no statistical association between the outcome of Masking Level Difference test and the following variables; age, sex, speech intelligibility degree and results of acoustic reflex testing.
A statistically significant relationship was observed between the phonological acquisition of phonemes/s/ and/?/ early-onset and/s/ and/z/ in medial onset with altered Masking Level Difference test results.
No statistically significant difference was observed for Masking Level Difference MLD, Adaptive Test of Temporal Resolution ATTR and Hearing-In-Noise- Speech Reception Threshold HINT- SRT p> 0.05.
To correlate anamnesis and evaluation we made an analytical cross-sectional study with 62 normal hearing with eight to 16 years submitted to anamnesis and staggered spondaic words test(ssw), pitch pattern sequence(pps),speech in noise and masking level difference(mld) tests.
When the masked thresholds obtained were at least 10 dB above the absolute threshold and the masking level used, the result was considered indicative of the presence of ZMC.
The relationship between Masking Level Difference test results and the variables: age, sex, degree of speech intelligibility, contralateral and ipsilateral acoustic reflex and the phonological acquisition of phonemes in initial and medial onset was analyzed in this study.
In another research,48 patients with complains of tinnitus were subjected to audiometric tests and to Minimum masking level MML, Tinnitus Handicap Inventory THI and Beck Depression Inventory BDI questionnaires.
The Masking Level Difference test consists of determining the hearing thresholds using a pulsed pure tone of 500Hz in the presence of a masking noise in two different conditions: noise and pure tone in both ears; and pure tone in both ears with noise in inverted phase in one ear.
We did not notice statistically significant correlations between psychoacoustic measures Pitch matching and Minimum Masking Level, audiometric data frequency with the worst threshold and cut-off frequencies and questionnaires validated to assess tinnitus Tinnitus Handicap Inventory and depression Beck Depression Inventory.
The Masking Level Difference test focuses on evaluating binaural interaction through the perception of acoustic signals in the presence of noise, while also indirectly assessing location and lateralization, quickly and efficiently, being a sensitive test to identify changes located in the lower brainstem.
