This sound is from Plastic door SFX Library

The metallic clang of keys jangling together echoed through the front of the building, signaling the arrival of someone new at the library. The distinct sound of a key sliding into the lock of the plastic door sent a shiver down the spine of the old building, as if it knew another day of stories and adventures was about to unfold within its walls. With a sharp twist, the door creaked open, the hinges protesting against the weight of its own weariness. The sounds of the outside world flooded in, mingling with the musty scent of aging paper and ink that permeated the library's air.

As the door swung shut behind the new visitor, the reverberation of its finality resonated within the space. The muffled click of the latch falling into place sealed off the outside world, cocooning those inside in a realm of knowledge and imagination. The plastic surface of the door pressed against the metal frame, creating a seal that no unwanted noise could penetrate. The faint rattle of keys being pocketed reverberated through the silence, a signal of the quiet solitude that was about to be found within the library's walls.

Inside, the distinctive sound of pages being turned filled the space, a symphony of rustling paper that spoke of countless stories waiting to be discovered. The metallic clink of shelves being pushed together harmonized with the distant hum of the library's old machinery, creating a backdrop of ambient noise that was oddly comforting. The glass windows cast gentle shadows across the plastic tables and chairs, creating a tapestry of light and dark that danced in time with the sounds of the library's inner workings.

Footsteps echoed against the tiled floor, the sharp click-clack of shoes punctuating the otherwise hushed atmosphere. The plastic chairs groaned in protest as they were pushed back, the metal legs scraping against the floor in a cacophony of discordant notes. The glass windows rattled slightly in their frames, a reminder of the outside world that lay just beyond the confines of the library's walls. But within this sanctuary of knowledge and learning, the outside sounds seemed distant and irrelevant, drowned out by the steady pulse of academia that beat within the library's core.

The sound of a pen scratching against paper filled the air, a hypnotic rhythm that spoke of thoughts being transformed into written words. The metallic whisper of a computer keyboard being tapped punctuated the silence, a modern-day symphony of productivity and creativity. The plastic door remained closed and unyielding, a barrier against the outside world that was only breached by the turning of a key. The glass of the windows reflected the soft glow of the reading lamps, creating a warm and inviting ambiance that beckoned visitors to lose themselves in the world of books and knowledge.

With a final click, the plastic door swung open once more, the sound of keys jangling in the lock serving as a farewell to another day spent within the walls of the library. As the visitor departed, the metallic clang of the door shutting behind them mingled with the distant sounds of the outside world. The library settled back into its quiet repose, the plastic, metal, and glass that composed its structure standing silent guard over the treasures contained within. The symphony of sounds that had filled the space slowly faded away, leaving only the memory of another day gone by in the hallowed halls of the library.
