Rule 1-6-1 changes and placards

NOTE: Each state association may authorize the use of a drum by a team composed of
deaf or partially deaf players, in order to establish a rhythmic cadence following the
ready-for-play signal.

Definition of Communication Devices
Communication devices are the machines that assist in transmission of data. The versatility of a computer gets enhanced considerably when it can communicate with other devices and computers. For a two-way communication, a computer must be equipped with a modulator for outgoing data and a demodulator for the incoming data. This modulating device is referred to as a modem. There are various kinds of communication devices in the present day market.

Nice try FBR but people have been communicating with non electronic devices for years.
