Infrasound has a frequency below normal hearing. Ultrasound waves have a frequency above the normal range of human hearing.
As you age you lose your ability to hear high frequency sounds first.
Not if they are at a different frequency, because hearing is frequency dependent.
Humans can hear sounds of 20 to 20,000 Hz. Hearing is best in the middle part of this range. However, the acuity varies between individuals and changes with age so that there is no specific frequency at which humans hear best.
Infrasonic.'Subsonic' and 'infrasonic' both define sound too low (in frequency or pitch) to be heard by humans without assistance.However, as 'subsonic' can also mean something traveling slower than the speed of sound, and 'infrasonic' only means frequencies below the audible range, 'infrasonic' is the better answer.
30KHz to 50KHz is the frequency range of hearing for a tiger.
A Pigeon has the lowest hearing Frequency at .1 Hz.
The lowest hearing frequency of a horse is 55 hertz, whereas the highest would be 33,500.
Human and ant hearing capabilities are very different from each other. The hearing frequency range for an ant is said to be 1kHz.

Frequency Theory
There are many things a person can't hear if they have high frequency hearing loss. They can't hear high frequencies.
