Space does not pass the sound of nothingness, no gas or other substances transmit sound waves, but travelers spacecraft signals can be monitored human ear can hear frequencies playback.

American Life Sciences website reported outside the boundary of interstellar space, the distant Voyager 1 spacecraft in Earth early this year call-back, mixed with the new environment noise.Indeed, the space does not pass the sound of nothingness, no gas or other substances transmit sound waves, but travelers spacecraft signals can be monitored human ear can hear frequencies playback.
In September, NASA announced that Voyager 1 in August 2012 left the heliosphere, which is the influence of the magnetic shell emitted by the sun, it flows through the expansion of charged particles called the solar wind. At a news conference, Voyager 1 plasma wave science instrument Principal Investigator Don Gurnett (Don Gurnett) shows the range of the device to monitor the sound. “Strictly speaking, the plasma wave device does not monitor the sound. Instead, it can be perceived through the ionized gas or Voyager’s ‘plasma’ in the electron wave,” NASA says in a statement. However, the frequency of these waves is not within the scope of monitoring the human ear.
“We can play these data through the speaker and listen carefully,” professor of physics at the University of Iowa Gurnett says. “Pitch and frequency gives us a clue spaceship surrounded density gases.”
Within the heliosphere, the sound frequency of about 300 Hz. Once Voyager left the heliosphere, click on the jump to a higher frequency, around 2000-3000 Hz, “and the interstellar medium in a more dense gas that corresponds.” Currently there are two cases have been confirmed about the tone of these examples: 2012 From October to November, and April 2013 to May. Both occurred in the great cause of CMEs near the Voyager 1 plasma activity swells after. Scientists have found that some of these recordings delay, because these data every 3-6 months to send back to Earth again, NASA said this, also needed more time to interpret these results.
Gurnett further speculated that the solar system other than the “shock front” could tear the interstellar space and disrupt nearby Voyager 1 plasma. He will pay close attention to the evidence coming in on the Voyager 1 recording these activities.
