Page 12: Proper Transducer Placement
Insert earphones have greater attenuation between ears especially at the low frequencies; this reduces the need for masking. 2. It is best to clip the insert earphone transducers behind the child or on the back of their clothing and then fit the foam eartip into the child's ears. Otometrics - AURICAL Aud... -
Page 13: The Masking Assistant
The environment in which sound-field audiometry is performed may affect the sound field near the patient. The performance of loudspeakers for AURICAL Aud was tested by Otometrics under free-field conditions in a large anechoic chamber. Sound pressure level, frequency response and distortion were measured by a microphone placed 1 m from the front of the speaker. - Page 14 Pure Tone Hearing Thresholds, Audiologists’ Desk Reference - Vol 1, James W.

HL Range The maximum output levels from AURICAL Aud depend on the actual sensitivity of the individual transducers, and they will be slightly different for each unit. However, the minimum requirements from IEC and ANSI standards are fulfilled for all units.
- Page 24 17 Technical specifications Distortion of signals occurs for higher stimulus levels. AURICAL Aud complies with IEC and ANSI standards with respect to maximum distortion.

For the applicable earphone models, the attenuation is specified in the following table.
- Page 26 The maximum speech output level from the bone oscillator depends on the actual sensitivity of the vibrator. The actual maximum output is therefore determined at the time of calibration. The actual maximum output level may be determ- ined by the operator by simply increasing the output level until the attenuator setting no longer increases. Otometrics - AURICAL Aud...
