What It Is

acousticscale.org is an academic wiki knowledge base maintained by the UK's CNBH (Centre for the Neural Basis of Hearing). Its theme centers on "bioacoustic communication"—how animal calls, speech, and music are produced, how the auditory system processes them, and how humans perceive them. Its core focus is the "size information" carried in sound, studying how the size of a sound-producing body affects the acoustic scale information within a sound.

Core Features

The site organizes its content around three sections:

• Bio-Comm Sounds: Explains two forms of size information—glottal pulse rate and vocal tract length.
• Auditory Processing: Based on the Auditory Image Model (AIM) proposed by Patterson and colleagues, with videos illustrating how the auditory system separates the fine temporal structure of sound (pitch, timbre) from the temporal envelope (auditory event dynamics). It also references two computational toolsets, AIM-MAT and AIM-C, implemented in Matlab/C.
• Auditory Perception: A collection of research papers and projects on the role of acoustic scale and auditory images in perception.

It is essentially a read-only knowledge repository. Unlike a traditional wiki, it isn't open for discussion or public editing—external contributions must be submitted in wiki format and added by the administrators after review.

Pricing

Completely free. It is a non-commercial academic public-interest resource, with no paywall or registration barriers whatsoever.

Pros and Cons

Pros: The content is fairly professional and in-depth within the niche field of auditory scale, accompanied by diagrams and videos, and it provides authoritative literature citations and links to computational models—offering clear value to relevant researchers.

Cons: The page was last modified in May 2014, so the content is clearly stagnant. The interface uses the old default MediaWiki style and feels dated. Its audience is extremely narrow, making it nearly useless for non-specialists. And since it isn't open for editing, community interaction is weak.

Who It's For

Suitable for researchers and graduate students in psychoacoustics, speech processing, and auditory neuroscience, as well as developers interested in the Auditory Image Model (AIM). Ordinary users have essentially no need to visit.

Access from China

The site is a static wiki with no apparent blocking and can be accessed directly. Loading may be slightly slow since the server is overseas, but this doesn't affect reading.
