What are horn tubes primarily used for?

Horn tubes are primarily designed to maximize high-frequency emphasis. This is achieved through their unique shape, which allows them to direct and enhance sound waves, particularly in the higher frequency range. The tapering structure of horn tubes acts to increase the efficiency of sound transmission, thereby making higher pitches more prominent.

In hearing aids and auditory devices, emphasizing high frequencies is essential, especially for individuals who may have a hearing loss that affects the clarity of speech, which is often in the higher frequency range. By focusing on high-frequency sounds, horn tubes help users to better perceive conversations and environmental sounds, significantly improving their auditory experience.

Other options, such as improving overall sound quality or maximizing low-frequency response, do not align with the specific function of horn tubes, which is primarily to enhance high frequencies rather than balance or improve all aspects of sound quality. Similarly, while reducing feedback is a critical consideration in hearing aid design, horn tubes don't specifically address feedback issues; their main function remains high-frequency amplification.
