Not necessarily. With many silencers the sound is actually louder at the shooter's ear than at the muzzle thanks to the extra gas coming back through the action on a semi-auto. Here are two examples out of many:

This can make a big difference in whether or not the shooter and bystanders are being exposed to harmful noise levels.
Regardless of where you measure it, a rifle with a silencer isn't anywhere close to "hearing safe" and will cause permanent hearing loss if you make a habit of firing it without hearing protection.
