Re: Roughness in audio and vision



A commonly used reference for measuring auditory roughness is a 1 kHz tone with a sine wave amplitude modulation at 70 Hz. The roughness of this sound can be modified by changing its modulation depth. A summary of this work is available in:


Zwicker E, Fastl H: Psychoacoustics : Facts and models, ed 2nd updated. Berlin ; New York, Springer, 1999.


In our own research on roughness perception in voices, we have used a somewhat different reference for quantifying roughness. We use a 150 Hz sawtooth wave mixed with some noise (SNR=12 dB) as the carrier signal. The amplitude of this carrier signal is modulated by a 40 Hz raised sine wave. The roughness of this signal can then be varied by manipulating the modulation depth.

I’m afraid, I have few ideas about manipulating roughness in visual images or the connection between auditory and visual roughness.

Hi everyone,


Some colleagues of mine are interested in  the relationship between roughness in visual images and audio images. They sent me the following questions they were thinking about in hopes that I might be able to provide some references to get them started.  I figured this is just the mailing list to get some pointers to papers. If any of these questions make you think of a paper or two, I’d appreciate your emailing  the reference.


1) Do we have a reliable method to measure the roughness of a given a natural sound or image?


2) How could one synthesis sound clips (and images) with ascending or descending order of roughness?


3) How can acoustic roughness influence the perceived roughness of the vision?



Thanks all!

While we are on the topic, I'd like to point list members to a really fine talk by Ani Patel on Music and the Mind for the UCSD show "Grey Matters".


Absolutely worth 51 minutes and 47 seconds of your time.

Dear List,

Last week I posted to the list about the upcoming music cognition
meeting in August (abstract deadline Feb 1):


I forgot to mention that some of you may be interested in the newly
published Oxford Handbook of Music Psychology (edited by Hallam, Cross, and Thaut):


This book has a remarkable range, with 52 chapters divided into 11 sections:

- the origins and functions of music
- music perception
- responses to music
- music and the brain
- musical development
- learning musical skills
- musical performance
- composition and improvisation
- the role of music in our everyday lives
- music therapy
- conceptual frameworks, research methods, and future directions

Note that a 20% discount is available at this website: http://www.oup.co.uk/sale/amohmp09/

This book, plus Bill Thompson's recent textbook on music cognition
("Music, Thought, and Feeling"),  provide wonderful new resources
for teaching and research in music cognition.
