The effective radius the pinger can be heard is around 22km in ideal conditions, so IF a sub was in or near that radius, then it's POSSIBLE that a sub may have picked up the signal. You asserted that it was picked up as fact. There's a massive gulf between the possibility an it being a stated fact.
Does your mysterious source provide any hard evidence of the location being known?
