Kid's Solution
Position modem with speaker facing upward. Pour pancake syrup into speaker. This will greatly reduce the high frequency response of the speaker thus attenuating the sound.

Call the modem manufacturer and demand that they supply you with a modem that defaults with the speaker turned off. If they refuse, sue them for noise pollution.
