The 1st heart sound lasts longer because the AV valves are less taut than the semilunar valves which will enable them to vibrate for a longer time
The second heart sound has higher frequencu due to semilunar valves are more taut and the great elastic coefficient of the taut arteries which provide the principle vibrations of the 2nd heart sound.
