Setting prescriptive targets Greg Nassar Clinical Scientist MCHAS RECD Refresher Course 17th 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-NL1 set-up screens • Calibrate new probe tube • Prepare coupler response
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 2cc- 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
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 EAR3 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
NAL-NL1 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
NAL-NL1 set up on Aurical • Same as previous but with additional control to select REAG or REIG
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 dB speech noise (modulated on Aurical) • 90 dB pure tone sweep • Program aid
