AUDIOMETRY MASKING RULES

Masking is used to stop one ear “listening” for the other one. It’s a bit like the way eyesa re tested. One eye is covered while the other is tested. We can’t do that with ears, so we need to introduce noise into the non-test ear to stop it from “listening”.

Air conduction masking rule:

Mask when:
• there is a 40dB difference between the air conduction threshold of each ear; or
• the better ear’s bone conduction threshold.

Start masking in the non-test ear at 10dB greater than its air conduction threshold.


Bone conduction masking rule:

Mask bone results when there is a 15dB difference between the better ear bone score and the poorer ear air score,

Start masking in the non-test ear at 10dB greater than its air conduction threshold.

Remember that masking greater than 40dB may result in over-masking.


Remember that with pure tone testing, you need to calculate the masking level for each frequency being tested.


How to do it:
1. Calculate the first amount of masking for the non-test ear.

2. Re-establish the threshold in the test ear while masking the non-test ear.

3. Each time there is a response in the test ear, increase the masking presented to the non-test ear by 5dB.

4. Each time the person does not respond to the tone presented to the test ear, increase the signal in 5dB steps (NOT the masking) until another response is observed.

5. Continue the procedure until the masking can be increased 3 consecutive 5dB steps without producing a shift in the threshold level of the test ear. When this happens, a "plateau" in threshold response has been reached.

6. At this point, record the masked symbol on the audiogram.

Audiometry MASKING ATURAN Masking digunakan untuk menghentikan satu telinga "mendengarkan" untuk yang lain. Ini sedikit seperti cara eyesa kembali diuji. Satu mata tertutup sementara yang lain diuji. Kita tidak bisa melakukan itu dengan telinga, sehingga kita perlu memperkenalkan suara ke telinga non-tes untuk menghentikannya dari "mendengarkan". Aturan masking Air konduksi: Masker ketika: • ada perbedaan antara 40dB ambang konduksi udara masing-masing telinga; atau • ambang konduksi tulang yang lebih baik telinga itu. Mulai masking di telinga non-tes di 10dB lebih besar dari ambang batas konduksi udara. masking konduksi tulang aturan: Topeng hasil tulang ketika ada perbedaan 15dB antara skor tulang telinga yang lebih baik dan telinga miskin Rata udara, Mulai masking di telinga non-tes di 10dB lebih besar dari ambang batas konduksi udara. Ingat bahwa masking lebih besar dari 40dB dapat mengakibatkan over-masking. Ingat bahwa dengan pengujian nada murni, Anda perlu menghitung tingkat masking untuk setiap frekuensi sedang diuji. Bagaimana melakukannya: 1. Menghitung jumlah pertama masking untuk telinga non-tes. 2. Untuk membentuk ambang di telinga tes sementara masking telinga non-tes. 3. Setiap kali ada respon di telinga tes, meningkatkan masking disajikan ke telinga non-tes oleh 5dB. 4. Setiap kali orang tidak menanggapi nada disajikan ke telinga tes, meningkatkan sinyal dalam langkah 5dB (TIDAK masking) sampai respon lain diamati. 5. Lanjutkan prosedur ini sampai masking dapat ditingkatkan 3 langkah 5dB berturut-turut tanpa menghasilkan pergeseran tingkat ambang telinga tes. Ketika ini terjadi, sebuah "dataran tinggi" dalam menanggapi ambang telah tercapai. 6. Pada titik ini, merekam simbol bertopeng pada audiogram itu.
