What could be wrong is after about five minutes of driving your car sounds like you have a flat but when you check it you do not but when you start driving again you hearing the thudding?
Hearing aids center on sound amplification, especially of voice and speech. A hearing aid contains three components - microphone, amplifier and receiver. The microphone catches the sound waves, taking in auditory sounds and consequently converting them into electronic sounds. To further detect these sounds, an amplifier is needed. It then takes the transmitted sounds from microphone and makes them louder.
When driving your subaru outback 2001 it sounds as if you are dragging a chain Twice it made a loud thudding noise from the front passenger side?
My 2001 Subaru Outback does not have this problem. If it sounds like you are dragging something, look under the car to see if you are dragging something. Take a look at the plastic fender liners to see if one of those has come loose and is in contact with a tire. There is no amount of written advice that can come close to just examining the car to see what is dragging.
I wear two cochlear implants, so allow me to explain. After having extreme difficulty hearing with hearing aides my audiologist decided that I was eligible for the CI. After getting the surgery I realized that rather than just amplifying sounds the implants clarified sounds, so not only able to hear the sounds, I was able to "understand" them as well.
Human hearing is most effective in the range of about 20 Hz to 20,000 Hz. Slightly lower frequency sounds may be heard or "felt." Some sounds outside this range can be heard by some individuals. Some animals have a wider range of hearing, such as dogs who can hear higher pitched (higher frequency) sounds.
Loud noises such as the sound system of a concert, jackhammering, fire alarms...listening to loud music on your iPod... Years of being around these sounds(and more) will damage your hearing. It was explained to me : Your ear canal has a series of hairs(receptors),that can be flattened after years of loud noises. I am having to buy hearing aisds as a direct result of being exposed to loud sounds. Good luck!
