During a sound check, the technician sends the exact same frequency to both speakers while you listen. The technician starts at 20Hz and slowly increases it to 30,000Hz.

a) What is the lowest frequency where you will hear a minimum signal?

f = Hz

b) What is the second lowest frequency where you will hear a minimum signal? f = Hz

c) What is the lowest frequency where you will hear a maximum signal? f = Hz

d) What is the second lowest frequency where you will hear a maximum signal? f = Hz
