Cosmic noise occurs at frequencies above about 15 MHz when highly directional antennas are pointed toward the Sun or other regions of the sky, such as the center of the Milky Way Galaxy. Celestial objects like quasars , which are super dense objects far from Earth, emit electromagnetic waves in their full spectrum, including radio waves.
A whistler is a very low frequency (VLF) electromagnetic (radio) wave generated by lightning. [1] Frequencies of terrestrial whistlers are 1 kHz to 30 kHz, with maximum frequencies usually at 3 kHz to 5 kHz. Although they are electromagnetic waves, they occur at audio frequencies, and can be converted to audio using a suitable receiver.
Armond Arabshahi, known by his stage name Unlike Pluto, is an American singer, songwriter, music producer, and former DJ.He is mainly known for his song "Everything Black", released under the record label Monstercat in 2017, which he produced with Philadelphia-based vocalist and DJ Mike Taylor. [1]
An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
on YouTube " Dat " is a song by Jamaican singer Pluto Shervington , released as a single by him, on the Opal Records record label, in 1976. The single reached number 6 in the UK Singles Chart on 6 March 1976, staying in the charts for a total of eight weeks.
A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
The ethereal audio reminds me of wooden wind chimes rattling as a mass of land shifts, perhaps during an earthquake. It brings to mind the cracking sounds of a moving glacier as well.
So while threshold levels of for the microwave audio effect of 267mW/cm² for 1.3GHz and 5000mW/cm² 2.9GHz, respectively, were reported by Frey in 1961, for the peak amplitude (providing the pops) and would only give an average (sustained) power density of only 0.4mW/cm² and 2mW/cm² respectively [7] similar to current cellphones.
