Josh Jenkins has credited the vocal Crows crowd for his controversial goal at the end of the third quarter against at Collingwood on Thursday night.

Television replays showed the game clock had reached zero before Jenkins slammed the ball through for the goal, but the siren wasn’t heard by the officiating umpires – or many of the 50,051 fans packed into Adelaide Oval.

Jenkins was told of the situation after the game but said that in the moment he had no idea the quarter had ended – least of all before he kicked the goal that put the Crows 14 points up. The 21-point final margin will say it wouldn't have mattered whether it was counted as goal or not.

"I knew I had to try and get it onto my boot as soon as possible but I certainly didn't hear the siren at all so I guess I have to thank the 19^th man (the crowd) for that one because without them the umpires would have heard it," Jenkins said.

"The umpires can only blow the whistle and that's when the quarter ends so if it wasn't for the 19^th man they probably would have taken the goal off me."

The AFL confirmed on Friday that a goal was the correct call.

Football operations manager Mark Evans said the official time-keeper was adamant it was a goal.
 
"He says that the ball is kicked just momentarily before he presses the siren - so the goal is correct, that's very pleasing," Evans said.
 
Umpires referred the matter to an official video review, but Evans confirmed the video review system doesn't have audio.
 
The usual process of the emergency umpire alerting the field umpires that the siren had gone failed.
 
"The emergency umpire didn't hear the siren either in this case, so none of the umpires, none of the players and I'm sure half of the crowd didn't hear the siren," Evans said.

The siren is set to be 'beefed up' and modifications to umpiring communication are also likely after the confusion. He said the AFL would work to rectify the issue.
 
"It's a good challenge for us to have, as long as we can solve it," he said. 
 
"We think the solution here might also be to get some way of communicating directly to the umpire simultaneously as the siren (button) is pressed.
 
"We do have to make sure that the crowd and the people watching the broadcast, that they also get that certainty that the siren has gone."

After the match both Brenton Sanderson and Nathan Buckley said they didn't hear the siren and on Friday morning Jenkins too said he was oblivious to its sound.

Collingwood president Eddie McGuire vented on Triple M radio in Melbourne on Friday morning, describing the incident as a "complete debacle" and one that "makes the AFL look shambolic".

Evans said he'd had contact from McGuire.
 
"It was mostly done via text message and Eddie was very good at expressing his views," Evans said.
 
"I couldn't be more appreciative of the way Nathan Buckley conducted himself last night," he said.

Those responsible for Adelaide Oval's siren have no issues with its volume.

In fact, they claim the AFL rates it the loudest siren in the competition

Chief executive of the Adelaide Oval Stadium Management Authority, Andrew Daniels, told AFL.com.au there was nothing wrong with the siren.

Instead, he said the confusion was created simply by the incredible noise created by the 50,051-strong crowd.

"The Adelaide Oval siren puts out 105 decibels, the AFL requirement is 95 decibels. We understand from the AFL that it's actually the loudest siren in Australia," Daniels said.

"What we actually have is an incredibly passionate, loud lot of patrons who were totally involved in a great game of football and screaming for their club.

"We wear that passion as a badge of pride."

Daniels said the design of the stadium contributed to any difficulty umpires and players faced when listening for the siren in big games.

Adelaide Oval's grandstands all feature large concave roofs, which he said "seem to hold that sound in".

But with the siren already sounding at 10 decibels louder than the AFL minimum, Daniels said further increasing its volume could prove dangerous.

"We have to be careful that if you get above 105 decibels you don't make it damaging to people's hearing," he said.

"My understanding is that umpires have in-ear [speakers] and therefore they're getting the word from the timekeepers even if it's so loud."
