No, the hearing threshold is not constant for all individuals. It can vary based on factors such as age, genetics, and environmental influences. Additionally, hearing thresholds can differ across frequencies, with some individuals being more sensitive to certain sounds than others. As a result, normal hearing ranges can show significant individual variability.

How many decibles is a whisper?
A whisper typically measures around 20 to 30 decibels. This level of sound is considered very quiet and is just above the threshold of hearing for most people. In comparison, normal conversation is usually around 60 decibels.
What is renal threshold of glucose?
Renal threshold is what happens when there is an overabundance of glucose in the body, the blood glucose levels will then get above 170mg/100ml (normal is 70mg/100ml).
What is traditional afrikaans culture?
well one of my best friends is from this "culture" i believe that they're culture is just like a normal persons. afrikaans is just a language/dialect... but i may be wrong...
Between what decibel levels does instantaneous damage to hearing loss occurs?
{| ! colspan="2" | Sound levels of common noises | Decibels Noise source Safe range 30 Whisper 60 Normal conversation 80 Heavy traffic, garbage disposal Risk range 85 to 90 Motorcycle, snowmobile, lawn mower 90 Belt sander, tractor 95 to 105 Hand drill, bulldozer, impact wrench 110 Chain saw, jack hammer Injury range 120 Ambulance siren 140 (pain threshold) Jet engine at takeoff 165 Shotgun blast 180 Rocket launch |}
What are different normal forms?
There are 4 normal forms in databases. First normal form, second, third and fourth normal forms are there.
What is the range of the threshold of human hearing and the threshold of pain?
It varies from person to person. However - an accepted 'normal' hearing range is around 20 Hz to 20,000 Hz. The same goes for pain threshold - anything over 120 dB would certainly be uncomfortable for most people.
What is the hearing threshold of humans?
At the threshold of hearing the sound intensity is 10-12 watts per square meter equivalent to 0 dB. Our eardrums are moved by sound pressure variations and so are microphone diaphragms. Forget the intensity! At the threshold of hearing the sound pressure is 2x10-5 pascals or 2x10-5 newtons per square meters, equal to 0 dBSPL.
What are sound waves with frequencies above the normal human range of hearing?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
Sound waves with frequencies above the normal human range of hearing are called what?
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
What is meant by surpassing the renal threshold?
Type your answer here... It is nothing but surpassing the renal threshold of an individual above the threshold which was normal to that person in certain period.
What is the normal range of hearing for a elephant?
Elephants have very good hearing and sense of smell, but poor eye-sight. Their normal hearing range depends on the volume of sound.
Information processed below the normal threshold of awareness is called?
subliminal
What is an audiogram?
A graphic representation of one's hearing ability compared to normal hearing
How do you use threshold in a sentence?
The handsome groom carried his new bride over the threshold on their wedding night. In 1492, Europe was on the threshold of a new era in world exploration. The girl barely met the threshold for normal height and weight ranges.
What is the difference between dB SL and dB HL?
The "SL" in dB SL stands for "Sensation Level". The "HL" in dB HL stands for "Hearing Level". The difference between them is that dB SL is based on the hearing ability of an individual test subject, and dB HL is based on the hearing ability of an entire population of test subjects. 0 dB SL is the minimum level at which the test subject can hear a stimulus, usually a tone pip. The actual level will vary with frequency. If we refer to a level of, say, 40 dB SL, we mean a sound that is 40 decibels above a test subject's threshold of hearing. The dB HL scale is the mean dB SL of a large population (theoretically the world-population) of *normal hearing* people. They measured frequency-specific thresholds for alot of people, and averaged them to give the dB HL scale. Finally, dB nHL stands for "normalised hearing level". This is the same concept as dB HL, except the number of test subjects contributing to the average is smaller. It is standard practice for a Hearing Clinic to establish their own dB nHL scale based on all the normal-hearing test subjects they have had access to. This allows a clinic to ensure that the scale they use is correctly calibrated to their test equipment.
How can hearing be tested?
Hearing can be tested by a tests called audiometric tests, in which the patient is subjected to sounds of varying frequency and intensity and the amount of intensity that has to be raised above the normal level for that particular frequency is plotted on a chart.By this test, the threshold of hearing by air and bone conduction can be known and also type and degree of hearing loss can be assessed. There are various other clinical tests for hearing like finger friction test, watch test, voice test (these are obsolete now) and tuning fork tests- Weber's and Rinne's test.

First of all, it is not persons it is PEOPLE!
