The Bark scale is a psychoacoustical scale proposed by Eberhard Zwicker in 1961. It is named after Heinrich Barkhausen , who proposed the first subjective measurements of loudness. [ 1 ] One definition of the term is "a frequency scale on which equal distances correspond with perceptually equal distances.
Dog barking is distinct from wolf barking. Wolf barks represent only 2.4% of all wolf vocalizations, in warning, defense, and protest. [4] [5] In contrast, dogs bark in many social situations, with acoustic communication in dogs being described as hypertrophic. [6] While wolf barks tend to be brief and isolated, dog barking is often repetitive. [7]
The ERB-rate scale, or ERB-number scale, can be defined as a function ERBS(f) which returns the number of equivalent rectangular bandwidths below the given frequency f. The units of the ERB-number scale are known ERBs, or as Cams, following a suggestion by Hartmann. [ 3 ]

They sound similar to an alert bark, but they're talking directly to you, not staring at whatever danger they're sensing. Your dog's being firm with you -- give her a piece of your steak, she's ...
The pioneering work of Ladefoged [16] used the Mel scale because this scale was claimed to correspond more closely to the auditory scale of pitch than to the acoustic measure of fundamental frequency expressed in Hertz. Two alternatives to the Mel scale are the Bark scale and the ERB-rate scale. [17]
His bark is so unique that it resembles the playful chatter of a dolphin more than a typical dog. Users have flocked to the post, expressing their delight and amusement at the dog’s animated sounds.
As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the ...
