Trainer #4 - Audiometric Interpretation Slides

Pdf Summary

The document provides an overview of audiometric interpretation and related testing methods, which are essential for diagnosing and understanding hearing loss. Presented by Kristin Wadsworth, the agenda covers audiometric interpretation, speech interpretation, Quick Speech in Noise (QuickSIN) interpretation, and includes training tools and tips.<br /><br />Key elements in audiogram documentation include three methods: a single audiometric graph, individual ear graphs, and numeric tables, accompanied by a symbol key. Understanding the audiogram involves recognizing its orientation and the values on the X and Y axes, which relate to frequency and intensity.<br /><br />Complete audiometric testing protocols require air and bone conduction measurements across specific frequency ranges and involve tonal measurements. Effective masking is used in both air and bone conduction and speech testing to ensure accuracy. <br /><br />Audiometric interpretation involves identifying the degree, configuration, and type of hearing loss, classified by PTA (Pure Tone Average) thresholds. The document provides a detailed classification of hearing loss severity and symmetry, distinguishing between symmetrical and asymmetrical hearing loss patterns. Various configurations of hearing loss such as flat, sloping, and noise notches are described, each with unique characteristics and applications.<br /><br />The type of hearing loss—conductive, sensorineural, or mixed—is determined by the relationship between air and bone thresholds. The document includes tips for training apprentices, emphasizing a foundational understanding of ear anatomy and the principles of air vs. bone hearing.<br /><br />Speech interpretation tests like SRT (Speech Recognition Threshold) and WR (Word Recognition) provide further insight into a person's hearing ability, focusing on the lowest level at which speech can be understood, comparing scores over time, and making recommendations based on noise testing results.<br /><br />The document concludes with QuickSIN interpretation, which helps gauge a person's ability to hear speech in noise, offering insights into appropriate amplification strategies, and concludes with practical tips for training. The focus throughout is on enhancing understanding and providing precise diagnosis for effective audiometric management.
