Different dogs have different capacities in terms of the level of sound they produce when they bark. The unit to measure sound in decibels (dB) and that is what we will be using here in our calculation. Please note here that decibels actually represents the intensity of the sound and not the absolute volume. So let’s consider different options to learn how a single dog barks at a sound intensity level of various possibilities.
As per research in 2013, the loudest a dog can bark is 113.1 dB. On average, the sound level of dog bark is somewhere between 80 to 90 decibels. This sound range in decibels is as good or as loud as an average human being shouting. For our subject topic, we will be considering the average sound of a dog, which is generic and not specific to any breed of dogs.

The average sound of an average dog barking in kennels is between 95 to 115 decibels. This is mainly due to the acoustic properties of the architecture that produces excessive sound. Noise in that excessive range for a dog or of anything for that matter is considered as an occupational hazard. Any sound over 85 dB is dangerous for human hearing and can lead to the damaging of your eardrums, especially if exposure to such a high level of volume is prolonged.
Let’s take the average of the average range of the sound level produced with dog barking. That average level is 85 dB. Now, a question comes, will the noise level of the dog’s barking gets doubled if two dogs barks simultaneously. It may not be doubled but may increase somewhat differently.
You can say it will give rise to an annoying effect that may seem a little bit louder than the barking noise of one dog. This either because of the fluctuation of the sounds produced by the two dogs which may bark differently as per their potential.
It is because when the two dogs bark, the noise will cancel each other’s impact, it will give a mixed barking effect and may create noise with varying intensity but on average the level would be the same and would increase to some extent.
In such a case, the noise level would certainly be increased but it wouldn’t double up simply. The noise level may only get doubled to 170 dB if both the dogs’ barks at the same wavelength and at the same time.
This, in reality, is highly unlikely to happen. But, if it does, then the volume or noise level will get double. Otherwise, the actual noise level experience on average would be 85 dB + ‘n’ dB, where n >= 0 and < 85.
So ideally it should be getting doubled, but as per the reality, a single dog barks at a particular intensity level and reaches its maximum potential up to 85 DB but will not double up if there are two dogs barking at the same sound intensity either due to sound waves interference or other surrounding factors alongside the barking tone and sound bassness of the voice of a particular breed.
Similarly, this phenomenon is scalable with as many dogs that are added in the scenario, where each dog has the maximum capacity to produce a sound intensity level of 85 dB and to calculate the total voice, the formula discussed above would work. The maximum sound intensity produced would be 85 dB x K, where K is the number of dogs in the test case.
Remember, that the maximum sound capacity for K dogs will only be possible if all barks at the same wavelength and at the same time.
