The audiogram is usually obtained using a device called an audiometer. A pure-tone audiometer allows the practitioner to change the frequency of the sinusoid, change stimulus level (usually in 5-dB steps), route the sound to different transducers (earphone, maybe a bone vibrator, discussed later, or speakers), and to turn the signal on and off.

Bone-conduction pure tones are transmitted through the skull using a bone vibrator (oscillator) which is placed on the mastoid or forehead. Bone conduction stimulates and assesses the cochlea directly, bypassing the outer and middle ear. The goal in testing is to produce an audiogram which is a representation of data collected in a hearing test.

Take the thresholds for four frequencies (500,1000,2000,3000) for each ear and average them. Increase by 1.5% for each dB above 25dB for each ear. Multiply the better ear by 5 (to weight it more heavily). Add that number with the worse ear and divide by 6 …
Guidelines for Manual Pure-Tone Threshold Audiometry
https://www.asha.org/policy/GL2005-00014/
The method described, an ascending technique beginning with an inaudible signal, is recommended as a standard procedure for manual pure-tone threshold audiometry. Tone duration. Pure-tone stimuli of 1 to 2 seconds' duration. Interval between tones. The interval between successive tone presentations shall be varied but not shorter than the test tone.
Understanding and Interpreting Pure Tone Audiometry

PTA or pure tone audiometry is a hearing test accepted worldwide as a standard protocol for determining hearing levels or hearing loss. Prerequisites for this test: -> The individual undergoing this test should be 8 years and above. -> PTA should be done in an acoustically treated room with least noise interference.

When you look at an audiogram you will see the frequencies are arranged from left to right across the top (or bottom) on the ‘X’ axis. Decibels go from the top of the graph, (0 dB) for the softest sounds, to loudest sounds (100+dB), on the ‘Y’ axis. Symbols on the audiogram
