Crickets and frogs by a flowing stream, with a gentle wind.

Surf rolling in, with gulls and birds along the coast.

Layers of drizzle, light and heavy rain, and a distant storm.

From steam locomotives to subways and high-speed rail.

The friendly murmur of markets and shops.

A low, comforting purr. No meows.

Settle into the steady hum of an aircraft cabin.

Creeks, streams, rivers and waterfalls.

Distant wildlife across savanna, forest and tundra.

Cars, SUVs, motorcycles and trucks on the move.

Steam, motors, metalwork and textile machines.
