A Comprehensive Guide to Fitting Frequency-Lowering Hearing Aids

Please note: exam questions are subject to change.

1. What is the primary purpose of frequency-lowering technologies in hearing aids? To increase the overall volume of sounds To re-code high-frequency sounds into audible lower frequencies To eliminate background noise To enhance battery life of the hearing aid
2. What is one challenge in researching frequency-lowering technology? Limited patient interest Lack of diverse technology options Difficulty in standardizing control in studies High costs of hearing aids
3. What is one of the potential side effects of frequency lowering? Increased battery life Enhanced color perception Distortion of low-frequency sounds Reduced device durability
4. When considering frequency-lowering technology, audiologists must: Always use the highest possible start frequency Choose settings based solely on the age of the patient Consider the hearing loss and audible frequency range of each patient Prefer the most advanced technology regardless of individual need
5. In frequency-lowering technologies, the term “frequency transposition” primarily refers to which of the following? Reducing the overall volume of high frequencies Shifting high-frequency sounds directly to lower frequencies Eliminating high-frequency sounds Enhancing the clarity of middle frequencies
