Like anything else, that would depend upon where you measure the sound, among other variables. Many devices are calibrated according to how "loud" it is when measured 3 meters (10 feet) away, with standard temperature and pressure, in ordinary air.
The UL standard for CO and residential smoke alarms is a minimum of 85 decibels at 10 feet. If they are installed in a hallway, with carpeting on the floors, bedroom doors closed, and ordinary air seal around the door (i.e., not thoroughly insulated), this may not be enough to waken someone inside the room, in which case an additional alarm (or other alarm annunciator) should be installed inside the bedroom.

Why are smoke alarms so loud that it hurts my ears?
Smoke alarms are designed to be loud in order to alert people to potential danger and ensure they hear the alarm even if they are asleep or in another part of the house. While the high decibel level may be uncomfortable or even painful, it is necessary to grab attention and prompt immediate action in case of a fire. The priority is to ensure people's safety by making sure they can hear the alarm even in noisy or chaotic situations.

Manual fire alarm system at home?
A manual fire alarm system at home typically consists of fire alarm pull stations strategically placed throughout the house. In the event of a fire, a resident can activate the alarm by pulling the lever on the station, which will sound a loud alarm to alert everyone in the home to evacuate. This system allows for a quick and direct way to notify occupants of a fire and initiate the necessary actions to ensure safety.

Your smoke alarm goes off without fire occuring?
If the smoke alarm goes off because of steam or smoke from cooking, the alarm should be moved to a better location or a different type of sensor used. It is very dangerous to have too many false alarms because people tend to ignore them, until the one time it really is a fire, and then it may be too late. If a smoke detector makes an intermittent "chirp", not a loud and continuous alarm, it may be signalling that it is time to replace the battery. Smoke detectors should be replaced every ten years, even if they still seem to be working, since they are only designed for a limited useful lifetime.
Can 10 minute exposure to a fire alarm cause hearing loss?
It depends on the type of fire alarm and how loud it is set to and where it actually is. If it is a loud, high pitched alarm then yes it may cause some temporal hearing loss but I doubt permanent.

If your smoke alarm was on but no fire was persent and your neighbor took it upon himself to breack down your door who should pay for it?
==One Answer== I think you should pay for the damaged door. One might argue that you installed a fire alarm loud enough to roust the neighbors so you should bear the consequences if they responded to your alarm. If you don't want to alarm the neighbors that something may be wrong at your house then perhaps you should deactivate the alarm when you are not at home.
