Project Overview

Lead Audio Engineer role: Design a system for 200m coverage

Project Overview

Mathematical Model

  • Decibel formula: dB=10log(I/Iโ‚€) where Iโ‚€=10โปยนยฒ W/mยฒ
  • Inverse square law: I=P/(4ฯ€rยฒ) relates power to distance
  • Key concepts: Logarithmic functions, inverse square law

Sound Intensity Calculations

  • At 10m: 110 dB = 0.1 W/mยฒ (max safe intensity)
  • At 200m: 80 dB = 0.0001 W/mยฒ (min required intensity)
  • Speaker power calculation: โ‰ˆ126 Watts needed

Safety Considerations

  • OSHA limits: 110 dB = 30min max exposure
  • Required safety measures: Hearing protection, crew rotation
  • Monitoring: Decibel meters for real-time level checks
Safety Considerations
5

System Implementation

  • Speaker placement: Elevated, angled downward with delay towers
  • Power settings: 110dB front, 85-95dB mid-venue
  • Conclusion: Math models ensure safety and sound quality
