In a recent study, music played out loud was found to have an undeniable effect on couples: It led to more sex.
This is one of many intriguing discoveries yielded by a study supported by Apple and sponsored by Sonos, a company making WiFi-connected audio systems.
For one week, 30 families from around the world were observed going about their days as usual, with no music played out loud, according to Mashable.
Their homes were stocked with Apple iBeacons to track the proximity of family members to each other, smart watches to monitor their heart rates and several web cams.
Without the presence of music, family members rarely made eye contact or spoke to each other, even when they were in the same room.
Both children and parents seemed to be preoccupied with iPads or iPhones, which kept their heads down.
In the second week, the households were given Sonos sound systems, as well as subscriptions to Apple Music.
Video filmed during this portion of the study shows family members laughing together, singing, dancing and displaying much higher amounts of affection.
During the week when music was played out loud, families reported spending 13 percent more time together and 20 percent more time in closer proximity to each other.
The total increase in sex was significant -- to say the least -- at a staggering 67 percent spike.
In addition, families also reported they ate more meals together than usual.
Neuroscientist and author Daniel J. Levitin, who was involved in the study, attributed these findings to music's effect on the brain.
Previous research determined music triggers a release of dopamine and the neurotransmitter oxytocin.
Levitin reportedly said,
Sonos allows different music to be played in different rooms, but it's the act of sharing music with each other that appears to have brought the families together, according to Levitin.
He reportedly added,
These findings were released in accordance with Apple Music becoming available on Sonos.
