First let me say, always be careful with gas. Do all of the checks to make
sure there are not leaks etc.

The sound you are hearing is most likely the diaphragms in the regulator
vibrating. It is known to do this when the outside temp contrasts the
cooling effect of the expanding gas. It will do this some days (usually warm
humid days) and not on others. If it bothers you (does me) try this:

turn off the control knobs, (on the grill)
turn off the gas tank,
disconnect the line from the tank
open the control knobs (on the grill)
wait 10-15 min.
turn control knobs off
reconnect tank
open tank valve very slowly (so as not to trip the safety shut-off)
turn on front burner and light.
Of course do all this with the cover up!

you may need to repeat a few times to get it to stop.

This is also the procedure you use if the safety valve in the regulator gets
tripped. It will do this if you open the tank valve quickly with the control
knobs on the grill open. The sudden rush of gas will trip it sometimes.

It's explained in the manual you should have received with the grill.
