Intro -- 1The Audiologist and Hearing Aid Provision The selection and fitting of hearing aids has been associated with audiology since before audiology was called audiology. In fact, it is probable that the extensive work with hearing aids and aural rehabilitation by several individuals during World War II is what led to the coining of the words audiology and audiologist, but more on that later. In this chapter, we talk about how audiology is associated with the area of hearing aid fitting and dispensi -- 2Understanding the Hearing Aid Candidate Data from surveys conducted by the National Family Opinion (NFO) panel from over 80,000 households suggest that approximately 32 million, or about 10% of the U.S. population of approximately 305 million, have some degree of hearing loss. It is usually estimated that around 95% of hearing impaired individuals can be helped with hearing aids, at least for some listening conditions. For the current U.S. population, that would be about approximately 30.5 mi -- 3Speech Acoustics As we discussed in the preceding chapter, there are a large number of factors that are important when assessing and understanding the patient and hearing aid candidacy. As we describe in the following chapters, there also are a series of audiologic tests, both behavioral and self-assessment, that we overview. However, the most common reason patients seek help is because of difficulties in hearing and recognizing speech. There are many variables to consider for speech recognit.

4Pre-Fitting Tests Using Frequency-Specific Measures In the next few chapters, we discuss some of the pre-fitting tools that we use to assess the patient, the patient's hearing handicap, and their communication needs to begin making decisions regarding hearing aid candidacy and selection. Assessing communication needs for the purpose of hearing aid selection requires knowledge in several areas. Given the time limitations in a typical clinic setting, it is necessary that an appropriately small -- 5 Pre-Fitting Testing Using Speech Material In the previous chapter, we reviewed how pure-tone and narrowband signals can be used to obtain useful information prior to the fitting of hearing aids. And in Chapter 6, we review how pre-fitting self-assessment inventories also assist in treatment planning and counseling. Although both areas certainly are important, it is commonly recognized that the cornerstone of pre-fitting testing lies with speech audiometry. Not only is speech testing part of -- 6 Self-Assessment Scales for Pre-Fitting Testing To this point, we have discussed objective pure-tone, narrowband, and speech recognition tests that can be used during the assessment prior to the fitting of hearing aids. We recommend also using self-assessment inventories to complement the objective findings. That is, some type of formal questionnaire completed by the patient that relates to their hearing difficulty, communication needs, the use of hearing aids, and their candidacy in general.

7 Hearing Aid Styles and Fitting Applications To this point, we have discussed the general attributes of the hearing aid candidate, the importance of speech information and how it interacts with the environment, several objective tests that we can use to assess the candidates ability to process speech, and additional tests to refine our fitting. We have also reviewed the self-assessment scales that further define the patient's problems and listening needs, and also provide insight regarding th -- 8 Ear Impressions, Earmolds, and Associated Plumbing In the previous chapter, we discussed how the choice of hearing aid style not only affects cosmetics and available features, but also can have important acoustic implications. More specifically, we know that hearing aid style can have considerable implications for amount of gain, potential feedback problems, and issues related to the occlusion effect. Although the general choice of hearing aid style will impact these factors, how tightly and -- Endnotes Chapter 1 1.Leland A. Watson originally worked for the Sonotone hearing aid company in Minneapolis, but in 1937, he set out to manufacture audiometers and established the Medical Acoustics Tools Corporation (later changed to the acronym MAICO -- the word tools was probably changed to instruments). The Maico D5 was the first audiometer established by the American Medical Association (AMA) and the Nationwide Bureau of Standards. Maico began manufacturing hearing aids in 1938 and perhaps are.
