Tips: hearing aids styles:
Hearing aids have been available in four styles: body, eyeglass, behind-the-ear (BTE), in-the-ear (ITE)
Included in the category of ITE hearing aids are in-the-canal (ITC) and completely-in-the-canal (CIC) styles (all shown in the figures below)
While body and eyeglass style hearing aids were regularly used 40-50 years ago, they comprise only about 1% of all hearing aids marketed today
Instead, most individuals choose ITE (approximately 80%) or BTE (approximately 20%) style hearing aids
This transition in style, use, preference is occurring for a number of reasons, including the reduction in the size of the components, durability, cosmetic concerns on the part of the consumer
