Final answer:
The effect of noise exposure in the workplace is measured using a dosimeter, which records exposure in decibels (dB). The loudness of sound is described by the intensity level or decibel. Animals affected by 120,000 Hz would be those with higher hearing ranges, not humans.
Step-by-step explanation:
The effect of noise exposure in the workplace is typically measured using a dosimeter. This device calculates the noise exposure a person has received over a certain period of time. It measures in decibels (dB), which is the unit used to express the intensity level of sound. An audiometer is used to test hearing ability, while an octave band analyzer is used to measure sound across different frequencies. A sound pressure level meter can measure the pressure of the sound, but may not necessarily track exposure over time as a dosimeter does.When discussing sound, the loudness of sound is often described using the term intensity level or decibel. The sound pressure level is another decibel scale based on the ratio of the pressure amplitude to a reference pressure. It's worth noting that sound intensity levels and sound pressure levels can produce substantially different decibel readings.As for the animal query, an animal that can be affected by a sound of 120,000 Hz is typically one with a higher range of hearing frequency, such as some species of bats or dogs, rather than humans who cannot hear frequencies above 20,000 Hz.
