Question: When was the lead actress from White Noise: The Light born?

Context paragraphs:
White Noise (The Living End song): "White Noise" is the first single from The Living End's fifth studio album, "White Noise".  Released on 5 July 2008, after the "White Noise" track was the most added song on Australian radio in the weeks previous, it went on to top the Australian Airplay Chart.  The single was also released exclusively on iTunes and Nokia Music, with respective bonus B-Sides.

Chris Cheney: Christopher John Cheney (born 2 January 1975) is an Australian rock musician, record producer and studio owner.  He is the founding mainstay guitarist, songwriter and lead vocalist of the psychobilly band, The Living End, which was formed in 1994 with school mate Scott Owen.  Cheney wrote the group's top 20 hits on the ARIA Singles Chart: "Second Solution" / "Prisoner of Society" (1997), "All Torn Down" (1999), "Pictures in the Mirror" (2000), "Roll On" (2001), "One Said to the Other" (2003), "What's on Your Radio" (2005), "Wake Up" (2006) and "White Noise" (2008).  In 2004 Cheney joined the super group The Wrights which put out a cover version of Stevie Wright's epic 11-minute track, "Evie" as a single.  At the APRA Awards of 2009 Cheney won 'Song of the Year' for writing The Living End's track, "White Noise".  In 2005 he married Emma, the couple have two daughters and are co-owners of a recording facility, Red Door Studios.  In 2011 the Cheney family relocated to Los Angeles.

White noise machine: A white noise machine is a device that produces a sound that is random in character, which sounds like a rushing waterfall or wind blowing through trees.  Often such devices do not produce actual white noise, which has a harsh sound, but pink noise, whose power rolls off at higher frequencies, or other colors of noise.

Brownian noise: In science, Brownian noise (   ), also known as Brown noise or red noise, is the kind of signal noise produced by Brownian motion, hence its alternative name of random walk noise.  The term "Brown noise" comes not from the color, but after Robert Brown, the discoverer of Brownian motion.  The term "red noise" comes from the "white noise"/"white light" analogy; red noise is strong in longer wavelengths, similar to the red end of the visible spectrum.

Pink noise: Pink noise or ⁄ noise is a signal or process with a frequency spectrum such that the power spectral density (energy or power per frequency interval) is inversely proportional to the frequency of the signal.  In pink noise, each octave (halving/doubling in frequency) carries an equal amount of noise energy.  The name arises from the pink appearance of visible light with this power spectrum.  This is in contrast with white noise which has equal intensity per frequency interval.

Avengers (EP): Avengers is the second EP from rock band The Avengers.  Released by White Noise Records in 1979 after the split up of the band, it was produced by musician Steve Jones from the Sex Pistols.  It is also known as the "White Noise EP", a reference to the record label.  The "1983 album of the same name" features identical versions of "White Nigger" and "Corpus Christi", while there are different versions of the other two tracks.

Stochastic resonance: Stochastic resonance (SR) is a phenomenon where a signal that is normally too weak to be detected by a sensor, can be boosted by adding white noise to the signal, which contains a wide spectrum of frequencies.  The frequencies in the white noise corresponding to the original signal's frequencies will resonate with each other, amplifying the original signal while not amplifying the rest of the white noise (thereby increasing the signal-to-noise ratio which makes the original signal more prominent).  Further, the added white noise can be enough to be detectable by the sensor, which can then filter it out to effectively detect the original, previously undetectable signal.

White Noise: The Light: White Noise: The Light, also marketed as White Noise 2, is a 2007 supernatural horror thriller film, directed by Patrick Lussier and written by Matt Venne.  The sequel stars Nathan Fillion and Katee Sackhoff in the lead roles.  It is a stand-alone sequel to the 2005 film "White Noise", directed by Geoffrey Sax.  The film received positive reviews, but was not commercially successful, and failed to recoup its $10 million budget.

Katee Sackhoff: Kathryn Ann "Katee" Sackhoff (born April 8, 1980) is an American actress best known for playing Lieutenant Kara "Starbuck" Thrace on the Sci Fi Channel's television program "Battlestar Galactica" (2003–2009).  She was nominated for four Saturn Awards for her work on "Battlestar Galactica", winning the award for Best Supporting Actress on Television in 2005.

Tinnitus masker: Tinnitus maskers are a range of devices based on simple white noise machines which are used to add natural or artificial sound into a tinnitus sufferer's environment in order to mask or cover up the ringing.  The noise is supplied by a sound generator which may reside in or above the ear or be placed on a table or elsewhere in the environment.  The noise is usually white noise or music, but in some cases it may be patterned sound or specially tailored sound based on the characteristics of the person's tinnitus.
