A Detailed Investigation into the Effectiveness of Earcons
نویسندگان
چکیده
A detailed experimental evaluation of earcons was carried out to see whether they are an effective means of communicating information in sound. An initial experiment showed that earcons were better than unstructured bursts of sound and that musical timbres were more effective than simple tones. Musicians were shown to be no better than non-musicians when using musical timbres. A second experiment was then carried out which improved upon some of the weaknesses of the pitches and rhythms used in Experiment 1 to give a significant improvement in recognition. From the results some guidelines were drawn up for designers to use when creating earcons. These experiments have formally shown that earcons are an effective method for communicating complex information in sound.

An Investigation into the Identification of Concurrently Presented Earcons
In this paper we describe an experiment investigating the ability of participants to identify multiple, concurrently playing structured sounds, called earcons. Several different sets of earcons were compared, one “state of the art” set based on the guidelines of Brewster [1], and other sets of earcons modified to take account of auditory scene analysis principles. The effect of the number of co...

متن کاملProviding a Structured Method for Integrating Non-Speech Audio into Human-Computer Interfaces
This thesis provides a framework for integrating non-speech sound into humancomputer interfaces. Previously there was no structured way of doing this, it was done in an ad hoc manner by individual designers. This led to ineffective uses of sound. In order to add sounds to improve usability two questions must be answered: What sounds should be used and where is it best to use them? With these an...
