01
  • Identification of factors in the patient’s background that may put him at risk for hearing problems.
  • Identification of FDA red flags that would require a referral for medical evaluation.
  • Identification of other medical problems that may have an impact on the methods used for procedures and/or expected outcomes of hearing aid fitting.
  • Identification of family members’ concerns regarding patient’s hearing difficulties.
  • Exploration of patient attitudes and expectations of amplification.
  • Identification of problems with hearing and understanding.
  • Identification of daily activities and impact of hearing loss on lifestyle.
  • Identify impact of hearing loss on family, friends, and in the workplace.

Indication for Procedure

  • Individuals being seen for either hearing screening or hearing evaluation.

Procedure Methods

  • Typically consists of a combination of written answers to a series of questions, elaboration of those answers by oral questioning, and behavioral observation.
  • Areas covered include but are not limited to: family history of hearing loss, incidence and duration of childhood hearing-related illnesses, information regarding dizziness, loss of balance, or tinnitus, current medication/drug history, history of noise exposure and acoustic trauma. In addition it is critical to elicit family members concerns about patient’s hearing difficulties, the patient’s attitudes and expectations regarding amplification, and the patient’s own assessment of their hearing difficulties.
  • Additional areas that must be covered include but are not limited to questions regarding history of ear surgeries, diseases and treatments, information regarding past experiences with amplification, questions and observation regarding ear deformity, pain, sudden hearing loss, ear infection, disease, drainage or blockage requiring medical referral.

Test and Analyze Hearing

Expected Outcomes

  • Basic hearing evaluation is conducted to quantify and qualify hearing loss on the basis of perceptual responses to acoustic stimuli and to describe any associated communication disorders.
  • Results of the evaluation may result in recommendations for more advanced testing, medical referral, amplification consultation, assistive listening device consultation, or follow-up recommendations.
  • Speech discrimination tests are performed for additional information about a hearing loss.
  • Evaluation may result in recommendation for a medical referral, amplification, aural rehabilitation, and/or counseling.
  • Determine need for medical referral based on audiometric air-bone gap results.
  • Determine degree, type, and configuration of hearing loss from test results.
  • Hearing instrument efficacy will be determined by pre-post audiometric measures.

Indications for Procedures

02
  • Hearing evaluation may be done when a hearing screening is failed.
  • Hearing evaluation is generally prompted by self-referral, family referral, failure of an occupational hearing test, or referral from other professionals.

Procedure Methods

  • Hearing evaluation is preceded by eliciting the hearing history and assessing the hearing problem. This is followed by examination of the external ear canal and cerumen management, if necessary.
  • The standard audiometric tests consist of pure-tone air and bone conduction testing with appropriate masking using the TDH-39 standard. It is our recommendation that all providers move to the EAR-3 or equivalent insert earphones standard by July 1, 2005. Some professionals also choose to do loudness growth testing at this time.
  • Speech testing includes speech awareness and/or speech reception threshold tests, speech discrimination tests, and establishing MCL and UCL thresholds (appropriate masking used as required). In addition further information can be gained by doing unaided and aided sound-field discrimination tests and by testing binaurally as well as monaurally.
  • Special audiometric tests are performed for additional information about a hearing loss.
  • Evaluation may result in recommendation for a medical referral, amplification, aural rehabilitation, and/or counseling.
  • Procedures such as immittance audiometry (tympanometry and reflexes) are quite common.
  • Evaluate the reliability and validity of the test results.
  • Evaluate test results to determine the presence of collapsed ear canals.
  • Evaluate aided sound field measures and/or real-ear aided performance measures or Live Speech Mapping.

Analyze Hearing Aids

Expected Outcomes

03
  • In consultation with the patient and family, taking into account their lifestyle, special needs, hearing aid style, technology, and price category preferences, selecting the hearing aid that will best fit their needs.
  • Provide measurable results of improved hearing thresholds and ease of communication.
  • The appropriate specifications for the hearing aid will be selected.

Indications for Procedure

  • Individuals identified with hearing loss who have reached a level of acceptance regarding their loss that they are ready to seek help from amplification.

Procedure Methods

  • Determine hearing aid needed for severity, type, and configuration of hearing loss, keeping in mind the patient’s history, lifestyle, and audiogram.
  • Discuss with patient the various levels of technology and their different price categories to aid in determination of hearing aid selection.
  • Identify physical limitations affecting hearing instrument selection.
  • Prior to dispensing the hearing aid, verification of hearing aid performance is conducted via a listening check to rule out excessive circuit noise, intermittency, and/or poor sound quality.
  • Perform electroacoustic analysis to determine if hearing aid is performing according to manufacturer’s specifications.
  • Confirm telecoil function.
  • Programmable and digital hearing aids should be programmed prior to patient’s arrival to ensure integrity of programming system and hearing aids.

Fit, Adjust, and Service Hearing Aids

Expected Outcomes

  • Appropriate earmold/hearing aid shell configuration and material will be selected for maximum comfort and hearing aid performance.
  • Alleviation of a problem with physical or acoustic comfort (i.e., occlusion, loudness, discomfort)
  • Restore the aid to manufacturer’s specifications.

Indications for Procedure

  • Patient is being fitted for new amplification.
  • Patient or family report a problem with the function, comfort, or benefit being received from the hearing aid.

Procedure Methods

04
  • Assess ear canal for ear impression vis-à-vis size, length, and direction.
  • Perform proper ear impression procedures, e.g. otoblock placement.
  • Determine earmold/hearing aid shell configuration and material.
  • Examine surface of earmold and instrument for damage and sharp edges.
  • Perform physical fitting of coupler and instrument.
  • Appropriateness of physical fit should be assessed through ease of insertion and removal, cosmetic appeal, comfort, absence of feedback, placement of microphone port/ports and ease of volume control use when present.
  • Program selected hearing aids to patient’s baseline audiometric data.
  • Adjust/modify hearing instrument electronics based on patient feedback.
  • Make venting modifications as needed for reduction of occlusion effect and or to control feedback. Modify shell or ear mold for improved, more comfortable fit.
  • In the event the patient returns with a malfunctioning hearing aid, conduct in-office internal inspection of ear mold and instrument and take appropriate corrective action (suctioning wax and debris from receiver and microphone ports, cleaning corrosion from battery contacts, replace earmold tubing, etc.). Conduct electric current drain measurement of hearing aid. If in-office repair is not possible return aid to manufacturer for repair and offer the patient a loaner hearing aid to use while his is being repaired.
  • If the hearing aid needs to go to the factory for repair, and it is out of warranty, inform the patient of the charges and repair warranty.
  • Validation of fitting should be done either with sound field testing using frequency specific thresholds and/or aided speech discrimination and speech reception thresholds or with real ear aided measurements or with Live Speech Mapping.
  • Reprogram hearing aids based on patient feedback.

Counseling and Aural
Rehabilitation

Expected Outcomes

05
