Introduction

With the development of the field to diagnose hearing, hearing protection and rehabilitation for the purpose of the test levels, making use of the audiometer greatly increase plus. This allows to consider the audiometer as a series of specific independent functional units. By the provisions of these functional units will be able to make provisions The performance of various types of hearing devices with these units. GB/T 7341 comprises a series of parts, of which GB/T 7341.1 is the first in this series Part summarizes the pure tone audiometer requirements. Because Expand GB/T 7341 following several parts, now, this section only defines a pure tone audiometer required range. This section The point is that without a broadband noise as a masking noise signal. Broadband is now used only for masking noise signal associated with the language section, 7341.2 as described in GB/T . The performance version will be separated from the test prescribed requirements out, the purpose is to prove its consistency. Only when the test lab Actual expanded uncertainty of measurement results comply with the technical requirements of this section in order to be verified. This section Table 7 shows the maximum permissible expansion Exhibition uncertainty Umax values. Based on this basic phase, audiometer manufacturer to meet the tolerance and GB/T 7341.1-1998 prescribed with. Compared with the previous version, suitable for use in the audiometer tolerance increased Umax. Electroacoustic audiometry equipment Part 1. pure tone audiometer

1 Scope

This section provides general requirements audiometer, and the test method employs psychoacoustic by standard reference hearing threshold level of comparison Designed for the specific requirements of measuring hearing threshold level of pure tone audiometer. The purpose of this section is intended to ensure that. a) comply with the requirements of this audiometer is different, according to GB/T 16403 and GB/T 7583 the method described, for nominee Ear for hearing test in the frequency range 125Hz ~ 8kHz, especially audiometry should be able to obtain substantially the same result; b) The results represent the baseline hearing test ear hearing a valid comparison between the threshold; c) audiometer test signal generated scope, operation or testing of auditory function range of complexity are classified according to their.
