IHS Exam questions And Answers 2023 (Latest 100% Graded A) In general, mold modifications are as follows: - Venting affects lows, damping the midrange and horn effects boost highs. Basic verification involves: - checking MCL and UCL in quiet and noise. Sound field is - a controlled environment The configuration and height of the tympanogram can be a factor in deciding the proper matrix for the fitting of a hearing aid: - A high Typ e A tells us to decrease the output by 2-3 dB You cannot use feedback checks when - checking the telephone coil Verification procedures: - Check the accuracy of your fitting. The problems produced by excessive ambient noise are - greater for the lower frequencies than the higher frequencies The decibel is - a ratio between two intensities REUR measurement are taken in - an open human ear canal When a hearing aid is dead, you can check the receiver and microphone function by: - turning on the instrumen t telecoil The dividing line between the external and middle ear is the - tympanic membrane The cochlea, acting as a frequency analyzer, distributes acoustic stimuli to places along the basilar membrane according to frequency. This forms the basis of a h ypothesis called the: - Place Theory An organic disorder is when there is damage to: - The hearing mechanism, the neural pathways and the brain. The speed of sound in air, in feet per second, is : - 1100 Properly selected hearing instruments should allo w: - The patient to wear an instrument at a comfortable loudness level, improved communication and have better hearing aided. Crystal microphones and receivers: - are very fragile Which of the following is not a coupler used for measuring hearing aid performance? - Zwisks Ear Simulator Small diameter tubing of SIA hearing aids has the effect of : - reducing the high frequency gain The function of a microphone is to : - convert aco ustic energy into electrical energy Vent an earmold : - is the most common modification made on an earmold When a new hearing instrument has feedback at the patients comfortable level, the problem is usually: - too much wax in the ear canal With SIE -S hearing aids: - The only signal is from the hearing aid and phrase effects from a vent are not an issue. The most comfortable level is: - About 45 dB HL or 65 dB SPL for normal ears Any complex sound can be broken down into individual frequencies by a tec hnique known as: - Fourier Spectral analysis The adult ear canal: - rises upward and forward, then descends to the drum. An effective verification is: - a measure able improvement in communication Which of the following is not included in correct test p rotocols? - plugging the hearing aid vent to control feedback Most conducive losses: - Are medically correctable, display a breakdown or obstruction in middle ear and display good discrimination The T position on a hearing aid switch can be used to - amplify a telephone conversation, couple hearing aid into a loop inductor, couple directly into the audio of a radio or tv The following components can change or modify the frequency response of a hearing instrument: - a microphone Afferent fibers: - transmit from the cochlea to the brain. User satisfaction must include: - patient preferences The following measurements use SPL as a reference: - Probe microphones, sound field aided thresholds, and ANSI specifications Speech discrimination tests: - approximate a sample of speech sounds in an ordinary conversation. A formant is: - a frequency region within a complex tone wher e certain harmonics have relatively large energy. Malingering is a category of : - non organic loss Bone conduction threshold worse than air conduction thresholds may be caused by : - poor placement of vibrator, skull fracture, thickness of skull Part o f the basic law of electrical energy is : - protons attract electrons Some patients with binaural amplification can experience: - degredation effect The scala tympani is filled with: - perilymph The following is a transducer: - electret microphone A sensorineural hearing loss is due to a disorder in the: - Inner ear In pure tone testing, threshold means : - the lowest intensity the client hears 50% of the time. The ear, due to its physical characteristics, enhances which frequencies? - 2,000 - 5,000hz When performing aided sound field testing, what degree of angle (from the patient/client) is the speaker to be placed? - 45 Rather than asking a patient/client, "How does that sound?," which test can a hearing healthcare professional use to measure the change in a patient's/client's hearing? - APHAB A hearing healthcare professional completes a fitting of new open -fit technolo gy for a patient/client. Which outcome measurement tool should the hearing healthcare professional use to determine proper fit? - Real ear measurement Which validation method can be effectively performed in a sound field environment? - NU 6
