“…Since clinical masking is started from IML, knowing the size of the plateau width after it is important. However, it is not necessary to determine the total amount of plateau width in clinical audiometry [ 6 , 10 ]. Plateau width is important for at least two reasons: confidence in the masked threshold in the wide plateau and inability to determine the masked threshold in the very narrow plateau [ 9 ].…”

“…The mPW mentioned in this paper is equivalent to the adequate masking range (AMR) defined by Turner [ 10 ], which is the range of the masking noise level from IML to the maximum usable masking before overmasking (AMR=BC TE +IA-IML). Of course, the mPW can be in any part of plateau of the masking diagram.…”

“…Since the mPW equation was extracted from the masking diagram, it can be extrapolated to all audiograms. As previously mentioned, plateau width is affected by ABG, and according to Turner [ 6 , 10 ], the AC plateau width can be computed by the following equation:…”

Background and ObjectivesIn clinical masking, the plateau is a state in which the non-test ear (NTE) is completely masked by the noise and tone is heard only by the test ear (TE). At least 15 to 20 dB of plateau width is needed to obtain valid threshold. In the study, a part of plateau after initial masking level known as the minimum plateau width (mPW) was determined and compared by a new formula and the plateau searching method. Subjects and MethodsMinimum plateau widths of air conduction were obtained in 29 participants with unilateral and 30 participants with bilateral conductive hearing loss (CHL) aged 20 to 45 years old by using step by step plateau method and mPW estimation by the formula between two points of masking diagram [mPW=(N2-N1)-(T2-T1)] and then the mPW of two methods was compared for each frequency. ResultsThere was no significant difference between the minimum plateau width obtained by the plateau and formula methods for two given point of masking diagram in people with unilateral and bilateral CHL at octave frequencies from 500 Hz to 4,000 Hz. ConclusionsThreshold obtaining of TE by two tones for two noise levels delivered to the NTE is enough to estimate the mPW between these two noise points and it is not necessary that for clinicians to know the actual values of masking diagram components.

“…People aged from 15 to 65, living in Salvador city, with unilateral or bilateral hearing loss, compatible with the patterns: unilateral (the thresholds without the masking indicate unilateral conductive hearing loss, there is an apparent gap on the TE); bilateral (the NTE's AC thresholds, without the masking, are, at least, 25dB better than the TE's AC thresholds); symmetrical (the AC thresholds, without the masking, are equal -symmetrical -or show a deviation of less than 20 dB); bone-only (there is only the need of masking for bone conduction thresholds of one or both ears) 8.…”

TEMA: na audiometria tonal liminar (ATL) algumas situações dificultam a obtenção dos limiares auditivos para cada orelha separadamente, havendo a necessidade do mascaramento. O método Platô, é o mais utilizado há mais de quatro décadas. Em 2004, foi sugerido um protocolo de mascaramento em que o método Otimizado substituiria o Platô, em casos específicos. OBJETIVO: analisar a aplicabilidade dos métodos Platô e Otimizado, na pesquisa dos limiares auditivos. MÉTODO: participaram deste estudo 40 indivíduos, de 15 a 65 anos, com perda auditiva unilateral ou bilateral. Foi realizada a ATL por via aérea (VA) e via óssea (VO), para ambas as orelhas, sem e com a utilização do mascaramento, segundo os padrões unilateral, bilateral, simétrico e somente-ósseo. RESULTADOS: não houve diferença estatisticamente significante entre os dois métodos para a obtenção dos limiares por VA, para os padrões avaliados. Contudo, houve um maior percentual de diferença para o padrão simétrico, durante reteste de VA. Houve diferença estatisticamente significante entre os métodos Platô e Otimizado, para a obtenção dos limiares por VO, para os padrões: simétrico e somente-ósseo. CONCLUSÃO: o Método Platô pode ser utilizado para todos os padrões e o Otimizado é mais eficaz para os padrões unilateral e bilateral. Desta forma, é necessário que o audiologista saiba diferenciar os melhores casos para a aplicação de um dos dois métodos e assim, obter resultados fidedignos.

“…The masking method developed in this paper can replace the plateau method in most, but not necessarily all, masking situations. The limitations of this new method will be evaluated in the second paper in this series (Turner, 2003).…”

This is the first in a series of two papers on masking. The objective of these papers is to develop a masking protocol that provides valid measures of threshold and is, in general, faster than the plateau method. In this paper, a masking method is developed that can replace the traditional plateau method in most masking situations. This new method is optimized to require fewer masking levels than the plateau method. As a result, it can be significantly faster than the plateau method. There are some masking situations in which this optimized method cannot be used. This limitation will be evaluated in the second paper and an alternate masking strategy provided for use when the optimized method is not appropriate.
