What does high-frequency hearing sound like?
High-frequency hearing loss is a condition where people have difficulty hearing sounds between the 2,000 to 8,000 Hertz range. This means that certain high-frequency verbal sounds like ‘s’, ‘h’, or ‘f’, (the consonants) are more difficult to hear or distinguish from other sounds.
What frequency of hearing is lost first?
Hearing loss does not progress after noise exposure is discontinued. As hearing loss progresses, the rate of hearing loss decreases. Loss is always greater at the frequencies 3000-6000 Hz than at 500-2000 Hz. Loss is usually greatest at 4000 Hz.
What kind of sound is too high pitched for people to hear?
In theory, he said, they’re sounds that are too high-pitched for people to hear. But in practice, they’re sounds that are right on the edge of hearing for infants, young people, some adult women and other groups with particularly acute hearing.
Why does my car make a high pitched whirring noise?
Thanks very much. I hear a high-pitched whirring noise underneath my CX-9 and the noise is modulated by engine speed, i.e. the faster the vehicle travels, the higher the pitch of the noise. The noise sounds like an electric motor. It is amplified when the noise bounces against a wall that is close enough to the vehicle as it passes.

The noise sounds like an electric motor. It is amplified when the noise bounces against a wall that is close enough to the vehicle as it passes.
Why are ultrasonic waves too high pitched to hear?
Ultrasonics are not well-defined, Leighton said in an interview with Live Science before his talk. In theory, he said, they’re sounds that are too high-pitched for people to hear. But in practice, they’re sounds that are right on the edge of hearing for infants, young people, some adult women and other groups with particularly acute hearing.
Why do I hear a low pitched hum while driving?
While driving, you hear a low-pitched hum. As you accelerate, the noise gets louder—maybe it sounds like an airplane taking off—but after a certain speed the volume is consistent. When you make a turn, the noise gets louder; but if you turn the other way, it disappears. What it could mean: This is most likely a wheel bearing noise.
What kind of noise does a car make when you accelerate?
Your car makes a humming noise when accelerating While driving, you hear a low-pitched hum. As you accelerate, the noise gets louder—maybe it sounds like an airplane taking off—but after a certain speed the volume is consistent.
What makes a humming noise at certain speeds?
The humming starts off with a lower tone (almost like a small plane flying overhead) and gets louder at certain speeds (35-40mph; 55-65 mph). I have switched to neutral and even turned off the engine momentarily(after ensuring it is safe on a lightly traveled road) to be sure that it is not from the engine.
What does it mean when you hear a wobbling noise in your car?
While driving, you hear a wobbling noise—like an unbalanced washing machine on the high spin cycle. What it could mean: If you hear this sound, pull over right away, and check your wheels and tires. You may have loosened wheel nuts, which could result in the wheel falling off, or low tire pressure, which puts you at risk for a tire blowout.
