Sound is a universally recognized way to connect with others, not just by words, but through song and music. Sound can be a form of communication even in sub-audible ways, through silence or pauses, or vibrations like the feeling of blood coursing through our veins and the rhythm of our breath.
Connecting with people involves an exchange of information; information which can be exchanged in a thousand different ways, from the simple and remote to the complex and involved, from a handshake to a PhD dissertation, from a smile to a philosophical debate, from a clothing style to a political movement. Connection involves communicating something about yourself, communicating your observations of the world, or your observations about the other person, but without an exchange of information, in a total vacuum with zero communication, how can connection transpire?

Mark Pilkington, "The fear frequency," The Guardian, The key here is frequency: 19hz is in the range known as infrasound, below the range of human hearing, which begins at 20hz. Tandy learned that low frequencies in this region can affect humans and animals in several ways, causing discomfort, dizziness, blurred vision (by vibrating your eyeballs), hyperventilation and fear, possibly leading to panic attacks.
