For the third Decibels Challenge, the prompt for data is personal data. I decided to use data from 10 workouts I did and use SonicPi to sonify the process and Python to clean it up.

Wanted the sounds to represent the various stages a heart goes through in a workout. This explains some of the chaotic tension/feelings that can be heard in this track

Column Names

• HR_AVG - Average Heart Rate

• HR_Max - Max Heart Rate

• HR_Min - Min Heart Rate

• Calories - Calories Burnt

• CardioLoad - the cardio intensity given for that workout

• Zone2, Zone3, Other Zones - Refer to the Five Heart zones

• CaloLoad - Is the ratio of Calories Burnt: Cardio Load

These columns are used in the SonicPi Code to make the sounds and can be used to understand which columns are affecting which part
