BANG!!

Although a bang technically has all frequencies present :good: , the perception will be different for a dog than a human. Due to shape of ear it would be difficult to assess.

 

Best way to check, after several days shooting, whistle and see if it comes back :good:

 

 

I was sat in the hide this morning and shot a crow. you know when a cart sounds extra loud? i had one of those and thought "glad im not a dog". just wandering if dogs suffer from deafness due to loud noises.

:blink: Hmmm maybe a point about the floppy ears, my pointers and viszlas dont seem to be affected but I had an amazing couple of hours on the pigeons once getting through 150+ carts in 2 hours, with my jack russel next to me while i was kneeling, at one point a flock of at least 20 birds dropped into the deeks and I let of 5 very fast shots. The dog looked up at me and howled!!!!

 

Once we got her home, she would not respond to any amount of whistling or calling.....but was ok the next day :oops:

"Abstract : Concern for hearing impairment of Air Force personnel as a result of turbojet noise led Air Force veterinarians to speculate that similar impairment may occur among Air Force sentry dogs. It was the purpose of this project to develop and test canine ear defenders and to evaluate the feasibility of using them in Air Force dogs. Three basic types of ear defenders were developed: universal earplugs, molded earplugs, and external earmuffs. Eighteen dogs were used to evaluate the ear defenders under conditions ranging from acoustical chamber to flight-line runup of operational aircraft. Exhaust noise levels, as recorded, ranged to 128 dB at all frequencies (20 Hz to 20 kHz) and intake noise levels ranged to 115 dB at all frequencies. None of the dogs showed any apprehension to, or discomfort from, the noise without earplugs, although one dog gave evidence of somatic damage from the 128 dB noise level. It was, therefore, impossible to establish an end point for testing the protective devices. Earplugs were rejected as a means of protection because only 1 of the 18 dogs would tolerate them. Earmuffs were also rejected because the position of the canine ears precluded adequate application of the muffs. Recommendation was made to rotate and selectively station dogs found apprehensive of noise. (Author)

Thank you for posting. I can offer only empirical evidence as to dogs' loss of hearing from gunshot via a gundog organisation in the US called the "Hunting Retriever Club" (HRC). These were primarily Labs though all gundog breeds can be "tested" afield. The tests call for a shooter, with the dog, at his side in a hide to fire off three shotgun rounds (blanks but with the same volume as real rounds) in succession. It was found that many of these dogs had already lost much of their hearing by 3-4 years of age. The club turned to shotgun primers only instead of the blanks (known as "poppers") about five years ago, and since then the dogs seem to have retained their hearing into ripe old age.

 

Spaniels do seem to have selective hearing loss when it comes to the whistle. Of course, often it's preferable for them to keep their ears covered in different way

and thus out of danger of the handler's wrath...
