Can Sonification Become a Useful Tool for Medical Data Representation?

Area of Science:

• Medical Informatics
• Data Visualization
• Acoustics

Background:

• Sonification is an emerging technique for data representation through sound.
• Understanding the mapping between data features and auditory parameters (e.g., pitch, duration) is crucial for effective sonification.
• Existing sonification tools include tempolenses and artifacts like saccadic displays or loudness variations.

Purpose of the Study:

• To introduce and explore the concept of sonification as a novel method for data representation.
• To provide a theoretical background on mapping data to sound parameters.
• To discuss the potential future applications of sonification in the medical field.

Main Methods:

• Theoretical framework for mapping data to sound parameters (pitch, duration).
• Classification of sonification methods and description of sound display tools.
• Application of sonification to physiological data, including heart rate and ECG signals.

Main Results:

• Demonstrated sonification of heart rate (HR) and ECG signals, including HR variations during exercise.
• Developed and described procedures for evaluating the discriminant power of sonification algorithms.
• Presented examples of sonification for warning procedures.

Conclusions:

• Sonification offers a novel auditory approach to data interpretation.
• The study highlights the potential of sonification for future medical applications.
• Critical evaluation of the current state and future prospects of sonification in medicine.
