Setting prescriptive targets Greg Nassar Clinical Scientist MCHAS RECD Refresher Course 17 th November 2004

Prior to child arriving • • Select a client PTA (save and close as we don’t have PMS) Select appropriate hearing aid Open HA software (new battery, connect leads, switch on then…. ) • Open REM software – DSL [i/o] or NAL-NL 1 set-up screens – Calibrate new probe tube – Prepare coupler response RECD Refresher Course 17 th November 2004

DSL [i/o] set up on Unity • • • Access via the screwdriver icon Check DOB Transducer- how did you test hearing? HL to SPL- measured or manual RE to 2 cc- Measured or manaul Max Output (ULLs) Speech- UWO is specific child spectrum that takes child’s own voice into account (see Phonak Focus 20) Circuit- majority of HA on contract have fixed CR. If planning a linear strategy set to LINEAR Compr. Threshold- minimum or 40 -45 if WDRC strategy RECD Refresher Course 17 th November 2004

DSL [i/o] set up on Aurical • First screen • Check DOB • Transducer- how did you test hearing? – Sound Field (uses REUR for HL- SPL transform) – Insert/custom (used EAR 3 with earmould) – TDH- uses average REDD (discussed earlier) – ME Insert (more on this later) • HL to SPL- predicted or measured • HI type • Compression type- as before • Compression Threshold- as before RECD Refresher Course 17 th November 2004

NAL-NL 1 set up on Unity • Similar to DSLi/o except: – Number of hearing aids – Limiting refers to how MPO on hearing aid is adjusted (single channel or multichannel) – Earmould acoustics – Number of compression channels ((new DSL m[i/o]) – Uses BC values (new DSL m[i/o]) – Can measure REIR & REAG RECD Refresher Course 17 th November 2004

NAL-NL 1 set up on Aurical • Same as previous but with additional control to select REAG or REIG RECD Refresher Course 17 th November 2004

Hello young man! • • Otoscopy Tympanometry (if not performed during behavioural audiometry) • Measure RECD – Save session, then re-open from session list • Send him out/for a break/breather etc… • Attach aid to coupler – Close lid – 50, 65, 80 d. B speech noise (modulated on Aurical) – 90 d. B pure tone sweep • Program aid RECD Refresher Course 17 th November 2004
