NHS & PRIVATE HAs
A Coggle Diagram about OPEN CANAL FITTINGS
*The universal silicone tip comes in a variety of sizes.
*These achievements are due to:
-Faster Processing time available in Hearing Aids.
-Feedback Cancellation (Digital HAs can do this).
-There is now some low frequency gain compensation (!?), PROVISION OF NHS HEARING AIDS
Access to NHS and private provision of hearing aids.
Any Qualified Provider (AQP), PATIENT MANAGEMENT SYSTEM
-Paper Records for audiological notes.
-A computerised system for patient details.
PMS's (Patient Management system) is part of the modernised service.
2 options are used widely :
1) Practice Navigator
2) Audit Base, DEVICES: Custom Shell, Open, RIC & NLFC (?)
NHS & Private Adult Audiology Service Provision, QUALITY:
AUDITING AUDIOLOGY SERVICES
This is all about Quality Assurance where a service's compliance to recommended procedures & good practice guidelines are monitored.
The tools Used Are : a Quality Rating tool (QRT) and / or Quality Enhancement Tool (QED)
-The QRT is used in Scotland & Wales whilst the QET is used in England., HISTORICAL PERSPECTIVE - THE ANALOGUE NHS RANGE.
• Not a coherent 'range' as such.
*Generally the technology was less sophisticated than it is now.
• Currently free at the point of use.
• 10 series for mild to moderate losses. (up to 60 db HL across the speech range.) eg. BE 101MK2 & BE102HF
• 30 series for moderate to severe losses (~60 -80dB HL across the speech range eg. BE 301 , BE38)
• the 50 series for severe to profound losses (80 dBHL and worse ). e.g. BE54, BE 55D
*Body worn for severe to profound losses or BC aids or where BTE can't be used eg. BW82 BW83., (RIC) Receiver in the canal/(RITE) Receiver in the ear.
*The receiver is outside of the hearing aid casing, usually housed in the earpiece in the wearer's ear. The Aid & the receiver are connected by a thin wire ., (NON-LINEAR) FREQUENCY COMPRESSION HEARING AIDS
-These process and deliver high frequency speech sounds to the lower frequencies.
-The aim is to provide audibility of frequency regions that would otherwise be inaccessible using conventional straight-forward amplification.
-Who is a candidate? Patients with 'unaidable' thresholds for some frequency regions, usually the high frequencies but who have residual 'aidable' hearing in other frequency regions, typically low frequencies., SLOW FEEDBACK SUPPRESSION :
It could take 3 to 5 seconds to suppress feedback.
This might not be practical. and DIGITAL NOISE REDUCTION
This is reduced in the low frequencies.
(What is? The noise or the effectiveness of the Digital Noise Reduction?)
Therefore, on paper the overall effect of DNR is reduced but we aren't providing any gain in the low frequencies.
