“… African lions (Panthera leo) produce two distinct types of roars: the familiar, guttural one that anchors a roaring bout… plus an overlooked “intermediary” roar that is shorter and lower-pitched than the classic full-throated version.”

When the eyes stop finding depth and variation, thought flattens too. Sensory ecology predicts it: monotony is not calm, it’s starvation of information.

The Sounds That Built a City
What does your city sound like? Beyond the traffic and sirens, every city has a unique acoustic fingerprint – the chime of a specific metro, the calls of street vendors, the hum of industry. These sounds aren't just background noise; they're a vital part of a city's identity, woven into its history and our memories. But what happens when those sounds start to disappear? In this episode, we're putting on our headphones and exploring "The Sounds That Built a City." We dive into the fascinating field of acoustic ecology, learning how to listen to urban soundscapes and understand what they reveal about our lives. We'll uncover efforts to preserve our vanishing sonic heritage – the clicks, rattles, and roars of a bygone era. Join us on an auditory journey and discover the hidden symphony playing out on your streets every day. Are we listening closely enough to the sounds that define us?
