barking_vs_growling_etc
Growl Master BARKING involves treble or bassy yelps of a brief duration. The form is: VOWEL-consonant, with diminuation near the end.

GROWLING is a tenor or bass event only, but the duration is variable. Some growls are as short as a bark, yet other growls may outlast the universe itself. The form is also various, and may include accenture on vowels, consonants, or both, or neither. Various effects may be included in a growl. Growls, in general, are much more complex than barks, howls, or grunts.

HOWLING may occur anywhere from bass to contra-soprano. Duration must be longer than that of a bark; howls cannot be less than 2.25 seconds or they do not meet qualifications. Additionally, howls are vowel-only events. Howls may not include consonants, not even if it is a Y.

GRUNTING may also occur in various pitches, but is generally lower than alto. Grunts also must be brief; prolonged grunts may or may not become growls but after 1.1 seconds a grunt is no longer a grunt. Grunts are consonant heavy, and may only involve the vowels O, U, and a soft E.

GROANING, BAYING, and other gutteral expressions vary similarly, but these mostly fall outside my area of expertise, and so I shall refrain from commenting upon them here... for now.

ancient beast uuuurrrrrrrrrrrrrrrrrRRRRRRgh!

except for the fact that it makes my throat hurt for days afterwards anymore, i can occasionally produce a simultaneous growl/scream/roar that registers at about 95dB

when i was young i could sustain it at 112-115dB for 30 seconds at a time

i can also draw air backwards through my voicebox and make it resonate in a very low, prolonged growl similar to the audible portion of the noise some alligators and crocodiles make to call others
