I've been watching a discussion on another forum regarding the use of loud horns to deter dogs from chasing bikes. Some dissenters say that it is cruel since dogs can "hear so much better than humans" and such loud sounds can injure them. My question is, is it better stated that dogs have a greater range and sensitivity (lower threshold) for sound that humans do and they aren't necessarily going to be negatively impacted by an equivalently loud noise? In other words if I'm exposed to a 115-120 db blast (roughly what the horn in question can produce) am I less, more, or just as likely to suffer injury than a dog exposed to the same noise? Any insights?
