pure tone av·er·age (pyūr tōn av'răj') The average hearing threshold level for the pure tone frequencies of 500 Hz, 1 kHz, and 2 kHz. These frequencies are referred to as speech frequencies because many of the English phonemes are within this frequency range. The pure tone average...
She has a special place in my heart, and I always use her as an example that there is never an age limit when learning. She passed in the 60s, but never drove as she never felt the need to. Fast-forward to today, her husband was diagnosed with glaucoma, leading her to wanting to ...
Table: Normal or average IQ scores by age What is a good IQ score? IQ scores between 90 and 109 indicate a normal IQ range or average intelligence. Individual adults usually score somewhere between the 70-130 range, with 100 being the theoretical average. If you score above 130, then you...
For instance, the average male height for models is considered to range between 5'11" and 6'3", because a good height contributes to an impressive presence on the catwalk and suits most high fashion garments. However, that does not mean shorter people cannot make good and successful models...
Sonarworks added a slight boost to the bass response of all the headphones I tried; if you’re under 21 years of age, however, True-Fi won’t touch anything else. The older you are past 21, the more True-Fi compensates by boosting frequencies above 2kHz or so. Look at the screen ...

Sound pressure is often ‘A-weighted’ in spectrum before being compared to p0 [22], roughly reflecting the frequency dependency of human hearing sensitivity, which is indicated by a suffix to the unit: dBA or dB(A). b The A-weighted energy-equivalent sound pressure level in a given time...
