Quiet Frequencies

The waveform on Nadia’s monitor looked like a low shore: a dull hump of noise, a sharp spike where a door slammed, a rippling comb of someone’s keys. She rolled the wheel back and forth, listening to the hiss like snow falling against a window, the sound she could read as easily as other people read faces. The fluorescent light buzzed above her. In the lab’s glass, her reflection floated pale and double, a woman of twenty-seven with a braid slipping loose and under-eyes bluish from too much coffee and not enough sleep.

“Five seconds,” she murmured, tapping the spacebar. On the police recording, a man coughed. There was a bus braking outside. Somewhere an elevator coin-dropped. This was Tuesday, which meant she would process six more sets of unrelated sounds, send tidy reports, and pretend she didn’t hear the phantom singsong in the hiss, the child’s lullaby she never played for herself.

The courier left the envelope on her desk while she was in the kitchenette rinsing a mug. No sender’s name, just her own written in careful block letters, as if the writer had practiced on a pad. The paper smelled faintly of iodine and old paper, that library smell from years ago. She peeled it open with her thumbnail. Inside, a small cassette in a crackled plastic case. Handwritten on its spine in a darker ink: NADIA.

Her mouth dried. Old plastic held warmth, as if it had been kept close to a body. She walked back to her station, slid the cassette into the deck she kept for legacy files, and pressed play with a forefinger that felt too big.

The first second was a flood of air, a room-sized hush. Then the hiss settled into a bed. Underneath, faint as sleeves brushing, came a melody. No instrument, just a woman’s hum, the rising two notes and the falling three that had braided through Nadia’s childhood like the line between sea and sky. She clenched teeth against the burn behind her eyes.

“Who sent you?” she asked the desk, flat as a stone. Behind the hum, another noise appeared: a foghorn far off, slow and mournful. Gulls. The clink of halyards on metal masts. When the hum stopped, there was a man’s voice whispering a station ID broken by static, two words she had not said in ten years. “Skalniki… radio…” The tape clicked and ran on with hiss.

The hallway outside the lab smelled of toner and someone’s microwaved fish. Nadia returned the cassette to its clammy case, slid it into her bag, and signed out early with a lie about a dentist. The receptionist blinked, then went back to scrolling her phone, the buzz of video bleeding into the air. Outside, the sky had been shaved down to a flat steel lid. Wind shoved grit along the tram tracks. She walked fast without feeling her feet.

The tram’s doors breathed open. She took a seat by the back window and watched buildings pass: a glass bank, a bakery with steamed-up panes, an entire shop that sold nothing but bells. The city rattled with the same regular noise she had cataloged since moving here. It was easier to live where sounds were inventions and not memories.

At home, her apartment was as she left it: the fern drinking light on the windowsill, the pale blue sofa with one blanket thrown in a coil, the humming refrigerator with its familiar thin vibration that sat in the walls like a second pulse. She set the cassette down as if it might tip over and spill something corrosive.

She made tea and forgot to drink it. She paced. She tried to answer an email and typed the word “hiss” three times before deleting the entire line. When she finally pressed play again, she turned the speakers low and leaned in as if eavesdropping through a door. The woman’s hum seemed to ride inside the noise rather than float on it, as if it used the hiss as a river. She knew that voice. Not with the rational part of her that lists proofs, but the animal part that remembers the heat of a hand.

Her brother, Artem, picked up on the first ring. “Nadia? Hey, I was going to call. How’s the—”

“I got a tape.” The word broke ways when it left her mouth. “With her voice.”

Silence stretched, the kind with texture. “That’s not funny.”

“I’m not joking. It said ‘Skalniki’ on it.”

On his end, she could hear a kettle click, a window slide. Artem’s voice dropped. “You promised dad we wouldn’t start this again.”
