These are real pages from the book. The table of contents is the full one: 9 parts and 64 topics.
Practice session in your course. The instructor is watching you test a classmate at 2,000 Hz. They respond, and you blank: down 10 or up 5? And how many responses make it a threshold?
The course manual explains the threshold search in one long paragraph. Steps inside a sentence, with no order you can see. So with someone watching, you second-guess every tone.
In the book, the pure-tone test is one page: the steps drawn in order, with the numbers next to each one. Down 10 after a response, up 5 after none, threshold at 2 of 3 ascending responses.
The same goes for the 1,000 Hz retest, when to mask, the bone-conduction symbol for each ear and the standard threshold shift.
You look at the panel and know what to press. You run the test without going back to the manual.
The ear and sound, noise and the OSHA standard, setting up the test, pure-tone testing, reading the audiogram, masking, baseline and the STS, beyond pure tones, and a test-day toolkit: 68 pages, all illustrated
Think of it this way:
It's the annual test at the plant. This year's audiogram shows a dip at 4,000 Hz in the left ear, and you have to decide: retest, refer or just record it.
You open the page on baseline vs. annual and see the two audiograms drawn side by side, the shift at 2,000, 3,000 and 4,000 Hz averaged in a box, and the 30-day retest marked on the page.
Same with masking, the audiogram symbols, the noise notch, presbycusis and the tympanogram types: each one on its own page.
Audiometry Illustrated is 9 parts and 64 topics, all drawn, and it ends with a test-day checklist, the numbers to know on one page and one audiogram read in order.
What you see drawn, you don't have to memorize.
The outer and middle ear, the cochlea, air and bone conduction, hertz, the decibel, and dB HL vs. dB SPL vs. dBA.
How noise damages hearing, 29 CFR 1910.95 on one page, 85 and 90 dBA, the 5 dB exchange rate, noise dose and TWA, the NRR, fitting a foam earplug, training and records.
The audiometer with every control labeled, earphones and the bone oscillator, how quiet the room must be, daily checks, baseline rules, case history, otoscopy basics and instructions.
The frequencies you must test, the first tone, down 10 and up 5, what counts as threshold, the test order, the 1,000 Hz retest, bone conduction and tricky responses.
The audiogram grid, the symbols, degrees of loss, normal, conductive, sensorineural and mixed loss, the air-bone gap, the 4,000 Hz notch, presbycusis and asymmetry.
Crossover, when to mask air and bone conduction, the plateau method and the masking dilemma.
Baseline vs. annual, the standard threshold shift calculated, age correction with Appendix F, the 30-day retest, the 21-day notice, the OSHA 300 log and revising the baseline.
Tympanometry and its five curve types, speech reception threshold, word recognition score and the red flags for referral.
A test-day checklist, the most common testing errors, the numbers to know, a symbols and patterns cheat sheet and one audiogram read in order.
At the end of the book: A test-day toolkit: start-to-finish checklist, the numbers to know on one page and a symbols cheat sheet.
Practice plotting and reading audiograms (normal, 4 kHz notch, presbycusis, conductive, mixed) plus exam-style questions, all with answer keys, so you test yourself before the course does.
Each frequent mistake (loose earphones, a red-blue mix-up, testing too fast, forgetting to mask) sits next to the right step, on printable cards you can review in minutes before a test day.
