Subtracting 10 dB from ISO for the test performed at 1,000 Hz.
This is the correct answer because according to FMCSA guidelines,when recording hearing test results according to the American National Standards Institute (ANSI), the following decibels (dB) are subtracted from the International Organization for Standardization (ISO) hearing loss values: 14 dB for 500Hz, 10 dB for 1,000Hz, and 8.5 dB for 2,000Hz.
