Hi! Im working on a hobby project to calculate the rough distance of what the sound of thunder travels depending on the peakcurrent. In rough terms, could this table be used for making rough calculations if we consider optimal conditions or is there a peak distance that the sound can travel regardless the peakcurrent?

- Peak Current: 0-10 kA, Maximum Audible Distance: 2-4 km
- Peak Current: 10-20 kA, Maximum Audible Distance: 4-6 km
- Peak Current: 20-30 kA, Maximum Audible Distance: 6-8 km
- Peak Current: 30-40 kA, Maximum Audible Distance: 8-10 km
- Peak Current: 40-50 kA, Maximum Audible Distance: 10-12 km
- Peak Current: 50-60 kA, Maximum Audible Distance: 12-14 km
- Peak Current: 60-70 kA, Maximum Audible Distance: 14-16 km
- Peak Current: 70-80 kA, Maximum Audible Distance: 16-18 km
- Peak Current: 80-90 kA, Maximum Audible Distance: 18-20 km
- Peak Current: 90-100 kA, Maximum Audible Distance: 20-22 km
- Peak Current: 100-110 kA, Maximum Audible Distance: 22-24 km
- Peak Current: 110-120 kA, Maximum Audible Distance: 24-26 km
- Peak Current: 120-130 kA, Maximum Audible Distance: 26-28 km
- Peak Current: 130-140 kA, Maximum Audible Distance: 28-30 km
- Peak Current: 140-150 kA, Maximum Audible Distance: 30-32 km
- Peak Current: 150-160 kA, Maximum Audible Distance: 32-34 km
- Peak Current: 160-170 kA, Maximum Audible Distance: 34-36 km
- Peak Current: 170-180 kA, Maximum Audible Distance: 36-38 km
- Peak Current: 180-190 kA, Maximum Audible Distance: 38-40 km
- Peak Current: 190-200 kA, Maximum Audible Distance: 40-42 km
