Hearing aids which use conventional electronics have been the mainstay of the hearing aid industry for 35 years. Conventional hearing aid electronics use basic analog Class A technology to provide quality, linear-type amplification to patients with a wide range of hearing losses. Class A amplifiers have as their defining feature the characteristic of adding the same amount of amplification to all levels of sound intensity. Thus, low bass-type sounds will be amplified with the same amount of volume as high treble sounds. For this reason, some patients may find that conventional electronic hearing aids provide either too little sound or too much sound to comfortably reach a listening level for the particular hearing loss. When this is the case, the patient should consider a prescription circuit instrument of the advanced, programmable or digital technology type. Priced at the lower end of the cost pyramid, conventional electronics represent the most basic type of amplification and are a good choice when finances are the major concern.
