Sound in outer space
- Al contrario de la creencia popular de que no hay sonido en el espacio, este s铆 existe
- Contrary to the popular belief that there is no sound in space, it exists
Lloyd y Mitchinson explican en su libro El nuevo peque帽o gran libro de la ignorancia (2012), que incluso al estar cerca de una nube de gas interestelar, los 谩tomos que llegar铆an a nuestros t铆mpanos ser铆an tan pocos, no podr铆amos escuchar nada. Tambi茅n recalcan que tal vez alg煤n micr贸fono ultrasensible podr铆a llegar a ser capaz de captar estas vibraciones, pero el o铆do humano es realmente sordo frente a este fen贸meno.
Como estos sonidos no los captamos, esto quiere decir que est谩n por debajo de los 20 Hz, a estos sonidos no captados por nosotros son los que llamamos infrasonido. Como curiosidad la nota mas profunda jam谩s detectada est谩 en si bemol y la genera un agujero negro. Es 57 octavas m谩s grave que un do medio: m谩s de mil millones de veces m谩s grave que los l铆mites del o铆do humano.

Contrary to the popular belief that there is no sound in space, it exists (Parra, 2012), it is not audible, but there are infrasound waves since space is not totally empty. There are different types of gases, much less dense than the terrestrial atmosphere and allow the propagation of sound, in outer space we would hardly find two atoms per cubic centimeter.
Lloyd and Mitchinson explain in The Second Book General of Ignorance (2012), that even being close to a cloud of interstellar gas, the atoms that would reach our eardrums would be so few, we could not hear anything. They also emphasize that perhaps some ultrasensitive microphone could become capable of capturing these vibrations, but the human ear is really deaf to this phenomenon.
As these sounds do not capture, this means that they are below 20 Hz, these sounds not captured by us are what we call infrasound. As a curiosity, the deepest note ever detected is in B flat and generated by a black hole. It is 57 octaves more serious than a half do: more than a billion times more serious than the limits of the human ear.
