"The lower sound speed on Mars does not lower the pitch of the voice," "It makes the speaker seem slightly larger, but still in pitch. In fact, the atmosphere of Mars would raise the pitch of the speaker's voice slightly, because of a density effect."
Microphone missions
Other groups have produced simulations of extraterrestrial sounds, based on their own assumptions about atmospheric effects. The nonprofit Planetary Society actually helped set up experiments to record and send back sounds from the Martian surface — but one mission that carried the Mars Microphone failed (Mars Polar Lander, in 1999), while a French mission that was due to carry another microphone was canceled (Netlander). NASA's Phoenix Mars Lander had a small microphone on its Mars Descent Imager, but itproduced no data during that 2008 mission.

Leighton told me he didn't think the Planetary Society's simulated sounds were quite right, and he sent along a sampling of his own simulations. The differences between the sounds are actually subtler than I expected them to be, except for the Titanian waterfall, which actually sounds pretty alien. See what you think after listening to these sound clips:
- A reading of "Mary Had a Little Lamb," Earth-style
- "Mary Had a Little Lamb" on Mars
- Waterfall on Earth, and the simulated analog on Titan
- Simulated rumble of thunder on Earth, Mars and Venus
- Simulated crash of thunder on Earth, Mars and Venus
- The simulated winds of a Martian dust devil

The Bulgarian State Television Female Vocal Choir became widely known when the trend-setting English alternative record label 4AD released a pair of anthology albums in 1986 and 1988 with the now famous title Le Mystère des Voix Bulgares, their recordings date as far back as 1957. The first pressing of the Voix Bulgares album was the result of fifteen years of work by Swiss ethnomusicologist and producer Marcel Cellier and was originally released in 1975 on his small Discs Cellier label. Ivo Watts-Russell (founder of 4AD) was introduced to the choir from a third or fourth generation audio cassette lent to him by Peter Murphy, singer from the band Bauhaus.

- Psychoacoustics is the scientific study of sound perception. More specifically, it is the branch of science studying the psychological and physiological responses associated with sound (including speech and music). It can be further categorized as a branch of psychophysics.
- Surround sound is a technique for enriching the sound reproduction quality of an audio source with additional audio channels from speakers that surround the listener (surround channels), providing sound from a 360° radius in the horizontal plane (2D) as opposed to "screen channels" (centre, [front] left, and [front] right) originating only from the listener's forward arc.
- Surround sound works when 3 or more channels are used to send sound in multiple directions
- The first documented use of surround sound was in 1940, for the Disney studio's animated film Fantasia. Walt Disney was inspired by Nikolai Rimsky-Korsakov's operatic piece, Flight of the Bumblebee to have a bumblebee featured in his musical Fantasia and also sound as if it was flying in all parts of the theatre.

- “Musicians sort of knew this already—that the emotional center is not the technical center, that funky grooves are not square, and what sounds like a simple beat can either be sensuous or simply a metronomic timekeeper, depending on the player.”
PowerPoint may not be of any use for you in a presentation, but it may liberate you in another way, an artistic way. Who knows. -David Byrne

when you meditate, you are focusing on something, whether it’s a candle flame or your breath going in or out, or a mantra or a prayer. When you focus like that, the electrical patterns in your brain slow down and relax, and the amplitude of your brain-waves generally stabilizes in the alpha wave range. But it turns out that you don’t need to be a trained monk or meditate for weeks on end to be able to achieve this state of alpha brain wave relaxation. Instead, you can use a concept called “brainwave entrainment” to get the same effect. Brainwave entrainment is any method that causes your brainwave frequencies to fall into step with a specific frequency. It’s based on the concept that the human brain has a tendency to change its dominant EEG frequency towards the frequency of a dominant external stimulus (such as music, or sound). The type of sound frequencies that are typically used in brainwave entrainment are called “binaural” beats. The way that these work is that two tones close in frequency generate a beat frequency at the difference of the frequencies. I know this sounds complicated, but it’s pretty simple to understand when you think about it. For example, a 495 Hz audio tone and 505 Hz audio tone (whether overlaid in music or in a sound frequency) will produce a 10 Hz beat, roughly in the middle of the alpha brain wave range.
