The primary diagnostic test used to measure hearing is an audiogram, which is conducted through audiometry. This test involves various sound frequencies and intensities to determine an individual's hearing sensitivity. Additionally, pure-tone audiometry is commonly used, where patients listen to tones at different pitches and volumes to identify the faintest sounds they can hear. Other tests may include speech audiometry and tympanometry to assess different aspects of hearing function.

Diagnostic procedures are crucial for accurately measuring a patient's hearing loss as they help determine the type, severity, and specific characteristics of the impairment. These tests, such as audiometry and tympanometry, provide objective data that can guide treatment decisions and rehabilitation strategies. Additionally, understanding the underlying causes of hearing loss allows for targeted interventions, improving the patient's quality of life. Ultimately, thorough diagnostics ensure that patients receive appropriate care tailored to their unique hearing needs.
A stress test is one of the most commonly used tests to measure and assess cardiac fitness, as is an EKG (electrocardiogram).
Two tests that are commonly used to distinguish conductive hearing loss from sensorineural are Rinne's test and Weber's test.

An audiometer is used by a hearing instrument specialist or an audiologist to test and measure a person's hearing acuity or hearing level. It has an array of frequencies usually ranging from 250Hz - 8000Hz with decibel levels from 0-110 or sometimes 120dB. The patient is put in a sound proof booth with headphones, a tone is presented, and the patient usually presses a button when they hear the tone. The audiologist records the lowest possible level the patient consistently responds at to measure what is called their hearing thresholds.
The concrete slump test is used to measure an aspect of concrete. This test is used to measure the workable of concrete as well as its freshness and health.
Hemoglycotest is a diagnostic test used to measure the level of glucose in the blood. The results can indicate if a person has normal blood sugar levels, hypoglycemia (low blood sugar), or hyperglycemia (high blood sugar). This test is commonly used to monitor and manage conditions like diabetes.
