11REM Screen Setup

11.1Section overview

To accommodate your working preferences, the appearance of REM screens may be changed in several ways.

This section covers the following topics:

11.2: REM right or left ear display	11.4: SPL or HL scale
11.3: Graph, table or 2cc target format	11.5: Hide or show REM curves

11.2 REM right or left ear display

The RM500SL can retain and display REM test results for two ears. To switch between left and right test results, press the <Left/Right> key.

11.3 Graph, table or 2cc target format

Most REM test screens may be viewed in graphic or tabular format.

vIn RECD, highlight and <PICK> [Format] to toggle between [Graph] and [Table] views.

vIn Speechmap and Insertion gain, highlight and <PICK> [Format], then highlight and <PICK> [Graph], [Table] or [2cc targets] from the drop-down list.

vIn [2cc targets] format, reserve gain and fitting formula may be changed. Highlight & <PICK> the appropriate window, then highlight & <PICK> the reserve gain or fitting formula from the drop-down list.

In Speechmap, if DSL or NAL-NL1 has been selected as a target method, then 2cc coupler targets for user gain, full-on gain and OSPL90 are provided. The full- on gain is just the user gain plus the reserve gain. If no target method has been selected, only 2cc OSPL90 values are indicated. Target gains are for speech- like signals at a 70 dB input SPL; OSPL90 targets are for 90 dB pure tones.

Real-ear targets are converted to 2cc coupler values by using age-appropriate average or measured (if available) RECD values and the appropriate microphone location effects for the desired style of hearing instrument.

The gain values given assume the hearing instrument is linear for a 70 dB speech input. This assumption is necessary to allow the microphone location effects to be incorporated.

For BTE and body aids, the 2cc coupler values provided assume a fully-occluding earmold with #13 tubing extending to the medial tip of the earmold. If a different type of mold is used, alterations to these values should be made to account for the different acoustic characteristics. For CIC instruments, the 2cc values take into account that the instrument, when deeply inserted into the ear canal, will produce a greater SPL in the ear than that measured in the ITE coupler.
