60 Hz power supply (US) is halfway in between Bb and B

50 Hz power supply (Europe) is a G#

International Distress Radio frequency is 500 KHz or a B

Hydrogen vibrates at 1,420 MHz which is an F

Magnetic resonance of Cesium's particle stream @ 9193 MHz is a C# (atomic clock)

DNA vibrates at a G

The Big Bang was an F#

Schumann resonance is a B (electromagnetic hum of the ionosphere)

Daily earth cycle is a G

The yearly earth cycle is an out of tune C# but is exactly Sa or Sadja in Indian music which has been 136 Hz for thousands of years.

The moon cycle is a G#, not a prominent note in Western music but the moon cycle vibration corresponding to 421Hz relates to the fact that in their day these composers tuned their A to these pitches:

  • Mozart A = 421.6 Hz
  • Handel A = 422.5 Hz
  • Bach A = 415.5 Hz
  • Berlin 1750's A = 422 Hz
  • Paris 1810 A = 423 Hz

    Frequencies of piano's range = 27.5 Hz to 4,224 Hz

    Wavelengths of piano range = 12.5 m to .081 m (8.1 cm)

    Frequencies of extreme range of hearing = 15 Hz to 20,000 Hz

    Wavelengths of extreme range of hearing = 22 m to .017 m (1.7 cm)

    C zero is the lowest standard note four octaves below the flute’s low C. It has a wavelength of 68 feet and a frequency of 16 Hz.

    Henri Bouasse demonstrated the existence of undertones in wind instruments in 1929. For more see Martin Vogel, The Theory of Sound Relationships.

    Speed of sound in:

  • air = 1,087f/s at 0 C or 1,130f/s at 20 C (68F)
  • hydrogen = 4,165 f/s
  • carbon dioxide = 846 f/s
  • water = 4,714 f/s
  • steel = 16,400 f/s
  • helium = 3,040 f/s
  • water vapor = 1,320 f/s
  • quartz = 18,000 f/s

    Speed of Light = 3x10 to the 8 m/s

    Conversational sound = 1,000 microwatts

    Threshold of hearing = 1/1,000 microwatt

    1 watt = 1 Joule/second

    60 dB = 10 microwatts

    Microwave window is 1-10 gigahertz (10 billion hertz)

    The Law of Octaves in loudness means the ear hears 1,000, 2,000, 4,000, 8,000 (in microwatts) as equal increments

    10X the watts sounds twice as loud to the ear

    Richter and Decibel scales are both by powers of 10

    The loudest sound ever created is the Resonant Macro-Sonic Synthesis system of Macro Sonics, generating pressure waves of more than 500 psi and amplitude louder than the space shuttle engines by a factor 100's of thousands of decibels.
