The controversial surgical procedure known as 'debarking' or 'bark softening' is a veterinary procedure for modifying the voice box so that a barking dog will make a significantly reduced noise. It is considered a last resort by some owners claiming that it is better than euthanasia , seizure, or legal problems if the matter has proven ...
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.
Here's what makes dogs bark at seemingly nothing at all. ... The fundamental frequency of mice is known to be around 40,000 Hz, while dogs can hear up to 60,000 Hz. ... What Is the Best Food for ...
This is the ratio (usually expressed in dB) between the noise floor of the device with no signal and the maximum signal (usually a sine wave) that can be output at a specified (low) distortion level. Since the early 1990s it has been recommended by several authorities including the Audio Engineering Society that measurements of dynamic range be ...
When a dog barks, the microphone records and transmits the sound to the hand-held unit for computer analysis by a database with thousands of dog barks pre-recorded into it. The unit then categorizes the bark into one of six distinct dog emotions (happy, sad, frustrated, on-guard, assertive, needy) and displays the corresponding emotion on the ...

A graph of the A-, B-, C- and D-weightings across the frequency range 10 Hz – 20 kHz Video illustrating A-weighting by analyzing a sine sweep (contains audio). A-weighting is a form of frequency weighting and the most commonly used of a family of curves defined in the International standard IEC 61672:2003 and various national standards relating to the measurement of sound pressure level.
