SUMMARY

This discussion focuses on the relationship between power (measured in milliwatts or watts) and sound (measured in decibels, dB SPL). Key formulas for converting sound pressure levels to power levels are essential for feasibility studies on converting sound to electricity. Participants referenced online calculators, such as those found on Wikipedia and Sengpiel Audio, to aid in these conversions. The discussion emphasizes the practical applications of these conversions in telecommunications and audio recording technologies.

PREREQUISITES
  • Understanding of sound pressure level (SPL) in decibels (dB SPL)
  • Knowledge of power measurement in milliwatts (mW) and watts (W)
  • Familiarity with acoustic principles and sound energy conversion
  • Basic proficiency in using online calculators for audio measurements
NEXT STEPS
  • Research the formula for converting dB SPL to watts per square meter
  • Explore the principles of piezoelectricity for sound-to-electricity conversion
  • Investigate the use of sound level meters and their calibration
  • Learn about the applications of sound energy harvesting in telecommunications
USEFUL FOR

Acoustic engineers, electrical engineers, researchers in renewable energy, and anyone involved in sound energy conversion projects will benefit from this discussion.

can some1 teach me some formula on how to relate power(mW/W) to sound(dBv/dBSPL)?i need some formula about this two topics and relate them because we are having a feasibility study on how to convert sound to electricity and we need some formulas,i know its kind a hard to transform sound to electricity but we really need some help..hope many of you would reply need some feedback asap
