Ok, based upon feedback...

# Wait for the supplied number of seconds. If no argument is supplied,
# defaults to five seconds. If the EPAUSE_IGNORE env var is set, don't
# wait. If we're not outputting to a terminal, don't wait.
epause() {
    if [ -z "$EPAUSE_IGNORE" ] && [ -t 1 ] ; then
        sleep ${1:-5}
    fi
}

# Beep the specified number of times (defaults to five). If our output
# is not a terminal, don't beep. If the EBEEP_IGNORE env var is set,
# don't beep.
ebeep() {
    local n
    if [ -z "$EBEEP_IGNORE" ] && [ -t 1 ] ; then
        for ((n=1 ; n <= ${1:-5} ; n++)) ; do
            echo -ne "\a"
            sleep 0.1 &>/dev/null ; sleep 0,1 &>/dev/null
            echo -ne "\a"
            sleep 1
        done
    fi
}

If no-one screams, I'll go ahead with this tomorrow.
