From CNBH Acoustic Scale Wiki
This wiki is about bio-acoustic communication, that is, how animal calls and the sounds of speech and music are produced, how the auditory system processes them and how we perceive them. The wiki emphasizes the size information in communication sounds:
- how the size of the sender affects the acoustic scale information in the sound (see the figure below),
- how the auditory images constructed by the auditory system help us segregate the size information in a sound from the message of the communication, and
- the role of the acoustic scale information in the perception of source size and instrument register.
The description of Auditory Processing is based on the Auditory Image Model (AIM) of hearing (Patterson et al., 1995). There are computational versions of AIM written in Matlab and C. They are referred to as AIM-MAT and AIM-C, and they can be obtained from the SoundSoftware repository. There is tutorial that describes the stages of auditory processing simulated by AIM. It was written for the original Matlab version of AIM referred to as AIM2006, but it still provides a good introduction to computational audition.
The Auditory Processing section of the wiki provides an explanation of what is meant by the terms auditory image, auditory figure, auditory event, auditory scene and auditory object. It includes videos that illustrate how the auditory system separates the temporal fine structure in a sound (which we hear as pitch and timbre), from the temporal envelope (which we hear as the dynamics of auditory events).
The Auditory Perception section of the wiki presents research papers and projects which describe the role of acoustic scale and the auditory image and in auditory perception.
The wiki was set up as a common workspace for collaborative research on communication sounds, and as a repository for information on acoustic scale and auditory size. It is not intended as a discussion forum like the traditional wiki. So Anonymous users and Normal users cannot edit pages on the wiki or add pages to it. If you have relevant information that you think should be added to the wiki, please send it to us, and we will add a page or assign you editing privileges (Sysop users).
Anonymous users can read the public pages without the need to log in. They cannot read "restricted" pages or modify any of the pages. Normal users have the same privileges, but they log in and can save their preferences. To create and edit pages you need Sysop users privileges (and to read the content of restricted pages). If you think you need Sysop access, email .
To create an account and become a normal user, you need to send an email to providing your name, professional address, and a username. We will create the account as soon as possible, and send you a password and information concerning your account.
