Hello Community,
Many types of electronic alarm mechanisms are available, often on keychain attachments, which can be carried and sounded if you find yourself in trouble as a way of attracting attention and discouraging an assailant. Better models produce sound levels above 110 decibels.
As a device, such items are still only useful if kept immediately at hand. If you don't have it with you, or readily available, when assaulted, it won't do you any good. A positive side is that these devices are not offensive weapons and can't really be used against you like a can of pepper spray might be, should the attacker take it away from you.
Thanks and Regards,
