The Echo Test

Letter 23 of the Book of Forgetting

Dalia Shalev found me at the survey post that morning, her recorder clipped to her collar. She had the voice memo pulled up on her phone.

"I want you to hear this before I write anything," she said.

We sat at the counter. She pressed play. The release came, then the splash, clear as anything. I marked both on a scrap of paper. She did the same.

"Three seconds," she said. "Ordinary. But Liesl's stopwatch read four."

"So the delay isn't in the sound itself," I said.

"Or the sound isn't the same for everyone." She put her phone away. "I'm going to test her without her knowing what to listen for. You want to come?"

The old well sat grey in the morning light. Liesl stood at the mouth, her stopwatch in hand. Dalia had set up her phone on a small tripod at the edge of the grass, recording.

"Same as before," Dalia said. "I drop, you time. But this time I'm not calling the drop. You just listen and press when you hear the splash."

Liesl nodded. "Fine."

Dalia picked up a stone, weighed it in her palm, and held it out over the water. She let it fall without a word. The splash came.

Liesl pressed her stopwatch. "Four point one."

Dalia checked her phone. "Three point one. You're a full second late again."

"Even without knowing when the drop happened?" Liesl frowned. "So it's not my reaction to the release. It's the splash itself."

"Or something else," Dalia said. "I want to try one more thing. I'm going to drop a second stone, a smaller one, right after the first. See if you hear them both."

She picked up two stones. She dropped them a heartbeat apart. Two splashes came.

Liesl looked at the water. "I heard two."

"Did they sound evenly spaced to you?"

"Yes. About a second apart."

Dalia checked her phone. "They were a quarter second apart. You heard a gap that wasn't there."

Liesl stared at her. "So I'm hearing something different."

"Or something extra," Dalia said. "You might be hearing the real splash and then an echo, and your ear is timing the echo."

Liesl was quiet a long moment. "That would explain everything. The well, the fog, all of it. My ears are tuned to something that comes a second later."

"Like the babies," I said.

Liesl looked at me. "You think?"

"You asked why they hear sentences nobody taught them. Maybe they're hearing the same thing you are—the real sound, plus something behind it."

Dalia packed up her tripod. "I'll write what we have. The delay follows Liesl, not the tool, not the well. And it shows up even when she doesn't know when the drop happened. That's a fact."

"Not a good one," Liesl said.

We walked back toward town. At the plaza, Noa Hadar was waiting with her phone. She'd heard we were testing.

"Did it follow her?" she asked.

"From twenty paces, with no warning," Dalia said. "Still a full second."

Noa looked at Liesl. "Then it's not your reaction. It's what you're hearing."

"Or what I'm not hearing," Liesl said. "Maybe there are two splashes, and I only catch the second one."

Noa nodded slowly. "Then the babies might be hearing two voices. One real, one behind it."

"And they repeat the one behind it," I said.

No one had an answer. We stood on the plaza in the grey light, and somewhere a child would wake and speak again, and I still did not know what it meant.
