Q

What are solutions for feedback/ whistling?

A
  • Check for wax in ear canal – remove/refer for removal
  • Check patient can insert aid/earpiece correctly – reinstruct if necessary
  • Check the aid is working correctly – replace and re-programme
  • Check the type of earpiece being used – replace with less open earpiece or a tighter fitting mould or remove vent if necessary
  • Check aid settings – use REMs if possible.
  • Apply feedback manager if this is appropriate (but without affecting frequency response of the aid)

Q

What are solutions for no sound when the aid is on?

A
  • Otoscopy – check ear for abnormalities (eg wax)
  • Check the battery is working – replace if necessary
  • Check the earmould tubing/wax filter isn’t blocked – clear out if necessary
  • Check for condensation in the hearing aid hook and filters – could be blocking off sound channel.
  • Use stay-dry tubing in the earmould and/or a drying box
  • Check on/off switch is working – repair/replace aid if necessary
  • Check aid is working – replace if necessary
  • If everything is working as it should be then arrange another hearing assessment

Q

What are some possible causes and solutions for ‘I can’t remember how to use the controls?’

A

Causes:
* Client has forgotten which control is which
* Client has forgotten how to use the controls

Solutions:
* Reinstruct as necessary

13
Q

What are some possible causes why the tubing has come out of the mould?

A
  • The tubing has deteriorated and broken
  • The aperture for the tubing is too wide
  • The earmould has broken
14
Q

What are some possible causes of a broken aid casing or ear mould?

A
  • The aid has been dropped, chewed by a pet, put through the washing machine etc
14
Q

What are some solutions for the tubing coming out of the mould?

A
  • Retube mould – use tubing cement if necessary
  • Check mould isn’t broken – take a new impression if necessary
  • Check audiogram – consider an open fitting if appropriate
15
Q

What are some possible solutions of a broken aid casing or ear mould?

A
  • Identify problem with mould/casing – can it be temporarily repaired?
  • Take a new impression or replace tubing/receiver
16
Q

What are some possible causes of an aid/ear mould hurting when put in?

A
  • Incorrect tubing length
  • Poor impression = poor mould fit
  • Meatal tip is too long
  • Poor finish on mould or hearing aid casing
17
Q

What are some solutions for an aid/ear mould hurting when put in?

A
  • Check length of tubing – too short/too long?
  • Retube if necessary
  • Look for pressure points on concha/EAC – adjust mould/casing if necessary
  • Check for rough edges on the mould/casing surface – file down if necessary
  • Take new impression if necessary
17
Q

what are some possible solutions for an hearing aid/ ear mould keep falling out?

A
  • Check client’s ability to insert correctly – reinstruct if necessary
  • Check tubing length – adjust or retube if necessary
  • Check hook fits OK – consider alternative type if necessary
  • Take impression for new mould/aid
  • Try alternative hearing aid with better retention (eg ITE)
17
Q

what are some possible causes of an hearing aid/ ear mould keep falling out?

A
  • When? Bending forward = tubing may be too short. Talking = EAC moves when patient moves jaw allowing aid to fall out
    (ITCs/CICs).
  • Patient isn’t inserting mould/aid correctly
  • Mould or aid is a poor fit
  • Patient’s ear is very small and aid hook is the wrong size
18
Q

what is a cause of a patients voice being echoey/ boomy?

A
  • Occlusion effect
19
Q

what are some solutions for a patients voice being echoey/ boomy?

A
  • Check type of mould
  • Vent, increase length of meatal tip if appropriate
  • Consider changing to open fit or open mould if possible
  • Check aid settings – reduce gain if necessary
20
Q

what is considered changing batteries ‘too frequently’?

A

It usually means replacing batteries more often than the typical 7-14 days, depending on hearing aid power usage.

21
Q

What are potential causes of frequent battery changes?

A
  • Hearing aid is faulty – draining too much power
  • Hearing aid is very high powered
  • Hearing aid is using lots of power-hungry features
    (eg active feedback management, active noise
    reduction, automatically activated directional
    microphone settings)
  • Batteries are faulty – if only noticed since opened a
    new pack
22
Q

How can the issue of frequent battery changes be addressed?

A
  • Check power usage of aid – replace if necessary
  • Replace batteries
  • Check settings of aid and deactivate unnecessary
    features
  • Replace aid
  • Counsel wearer re power usage of aid
23
Q

what are some causes and solutions for a patient reporting ‘“I can’t remember which aid is for which ear”?

A

Causes:
* Client can’t remember how to insert hearing aids
* Client removed moulds for cleaning and can’t work out which hearing aid goes on which side

Solutions:
* Reinstruct client about aid insertion and how to tell aids apart
* Assign red (right) and blue (left) markers to hearing aids
* Instruct significant others
