400 Hz in frequency (audible tone) its output is connected to electrodes 1 and 2 in the audio plug of the first phone through a 15 kΩ resistor as explained earlier. In the second phone a 400 Hz tone must be heard. Then, a frequency sweep is made -keeping the 100 mV amplitude in all the frequencies—from 50 Hz up to a frequency which the listener

10.4.2 Telephone and telegraph By international agreement the audio frequency for a commercial quality speech circuit routed over a multi-channel telephone system is restricted from 300Hz to 3400Hz. The suppression of all frequencies above 3400Hz reduces the quality of sound but does not affect the intelligibility.
