They usually check students’ vision and hearing on Fridays. Since last Friday was a down day due to the storm Hermine, I was able to assist with hearing screening. I had to ask a student to put the headphones on, handle them a knob, and say to press it any time they hear any noise or a beep. First, I had to measure frequency at 500, 1000, 2000, and 4000 Hz and volume at from 25 to 30 dB. Frequency range of 500-400 Hz is critical for hearing and understanding speech. People usually speak at intensity of 25-30 dB. Then, evaluate the result on the paper if a student has passed the hearing test. All of the school students passed hearing check. I had been promised to assist with the vision check next
