High-frequency hearing loss may cause difficulty in understanding speech, and the inability to hear birdsong, bells, and some musical instruments. The demand for the volume of TV and radio will also become higher and higher. High-frequency hearing loss will lead to social withdrawal, decreased work efficiency, and mental stress in the later stage.
Mid-frequency hearing loss often makes it difficult to understand conversations, especially in noisy environments or when multiple people are talking. Because there are many mid-frequency ranges in the human voice, it is often necessary for others to repeat the conversation multiple times, and it is difficult to distinguish between words that sound similar.
Low-frequency hearing loss is different from high-frequency hearing loss. It makes people unable to easily detect that they have hearing loss. It makes people feel that the sound has lost its thickness, power, and weight. It is easy to miss the low alarm sound, and the male voice sounds unclear.
