The water is beginning to simmer in the metal boiler. You know the heat is building because the giant vessel pings and tics as the increasing temperature causes it to expand ever so slightly. The highly sonorous characteristics of metal can be relied upon to produce tones that feel familiar and comforting.

There is something powerful, yet soothing, about the sound of an idling engine. It feels solid, reliable, built to last. Each component moves with precision, over and over, unceasingly. The steadfast rhythm is mesmerizing, lulling the listener into a placid, restful state. Relax and enjoy the calm.

The drone of the ceiling fan whirs overhead; the monotonous rush of air feels so comforting. Even the persistent tapping of a wobbly blade is reassuring; sometimes constant sound is exactly what we need to maintain equilibrium.

The speedboat engine is steady and strong, powering you across the surface. Waves form in the boat’s wake, slapping the hull as it carves cleanly through the water. Every now and then – a tiny moment of silence when the boat catches air. The wind rushing past your ears creates a dull roar that is somehow insulating and comforting. It’s a good day to be out on the water.

Your auditory senses are soothed by the rhythmic hum of a lawn mower in action. Imagine a warm Sunday afternoon, the distant, comforting drone of the mower gliding steadily back and forth across the yard, lulling you into a place of nostalgia and peace. Even the smell of the grass clippings seem to play a part in this suburban symphony. The monotony of the familiar sounds transport you to a realm of relaxation. The sounds weave a comforting sonic tapestry, calming your anxious thoughts, and guiding you toward serene sleep or a meditative calm.

It’s a warm, sunny afternoon when inspiration suddenly strikes! Sitting by the open window, you hear a gentle breeze rustling the leaves and birds singing outside. Insert a blank page into the typewriter and get to work! Each tap of your fingers creates a distinctive click as the keys strike the platen. The margin bell sounds, reminding you to advance the paper and begin a new line. You feel inspired, motivated, productive! Your fingers dance across the keys, creating rhythm and flow. Soon you reach the end of the page, and it’s time to load another pristine, white sheet. The new page may be blank, but in your mind’s eye, you see the possibilities.

Slow and steady…a monitor verifies the patient’s heartbeat. The rhythmic drone is reassuring, communicating that all is well. As you sit here quietly with your loved one, you observe the busy-ness of caregiving. There are so many details! Sterile supplies are unpacked and refilled, charts are updated, housekeeping is performed, phones ring at the nursing station down the hall. Nearby, you overhear doctors discussing a case, and a gentle nurse assisting a respiratory patient. The atmosphere is calm, orderly, and efficient. Rest assured, the patients are in good hands.

The steady flow of chilled air circulates all around you as the sturdy compressor supplies the refrigerant. When the vapor evaporates, it takes the heat with it, leaving behind an icy Arctic environment. Luxuriate in the cool, refreshing sensation.

The ferry’s powerful engine rumbles as the vessel steers into the harbor. Wavelets slap the hull when the boat enters the widest part of the channel. Cool, salty breezes feel refreshing, adding to the delight of being out on the water. Gulls wheel overhead, their high-pitched cries piercing the aquamarine sky. The combination of wind, waves, and sunshine is healing – melting away stress, leaving you feeling relaxed and peaceful.

The subway has a sound profile uniquely its own. The curves of the tunnel echo back the scrape of steel wheels on the tracks. Brakes squeal as the train slows, arriving at the next station. Another train pulls through, vibrating and rattling as it passes. Inside the car, exterior noises are muffled, overtaken by the sounds of conversation and passengers shuffling quickly on and off the train. On the subway you are free to engage, or just sit quietly with your own thoughts, alone, but not lonely, in a crowd.
