1. What does “frequency” mean in a hearing aid?
In simple terms, frequency refers to how high or low a sound is:
Low frequency = deep, bass sounds like a man’s voice, engine noise, or thunder.
High frequency = sharp, crisp sounds like a child’s voice, birds chirping, or the letters S, F, and T in speech.
2. What is the difference between high-frequency and low-frequency modes?
High-Frequency Mode:
Amplifies high-pitched sounds to make speech clearer and sharper.
It helps users hear consonants and speech details better, especially in quiet places.
Low-Frequency Mode:
Emphasizes lower-pitched sounds, making voices warmer and fuller.
It can make the sound more comfortable in certain listening environments.
3. Which mode is better for quiet environments?
In quiet environments, high-frequency mode performs better because:
It enhances speech clarity.
You can hear small details in conversation, TV, or nature sounds more clearly.
4. Which mode is better for noisy environments?
In noisy environments (like restaurants or streets):
The hearing aid automatically reduces low-frequency background noise (such as traffic, air conditioning, or crowd noise).
It does not switch to a low-frequency mode, but rather suppresses low frequencies while keeping high-frequency speech clear.
5. So, do high and low frequencies relate to noise or quietness?
Not directly.
Frequency modes are about what kind of sounds you hear better (high vs. low tones).
Noise control is about how the device manages background sounds.
Both systems work together to create a clear and natural listening experience.
6. Do Jiajianle hearing aids support both high and low frequency modes?
Yes. Our hearing aid models J-968, J-966, J-965, J-963, J-962, J-883, and J-881 are all equipped with H/L (High / Low) frequency selection.
Users can choose the suitable mode according to their hearing
