Questions extracted from the papers in this topic, excluding the curated questions above.
- How did researchers isolate which parts of the sound caused the strongest discomfort?
- How did the SpeechJammer device use delayed auditory feedback to interrupt someone talking at a distance?
- How did the alligator's bellow change under helium, and what did that confirm about resonance theory?
- How precise is bat echolocation normally, and what can it detect at a distance?
- What delay interval between speech and its playback is disruptive enough to silence a speaker?
- What does the acronym FRT stand for in the herring bubble-sound research?
- What evolutionary explanation did the team propose for why this sound is so aversive?
- What happened when researchers subjected a live earthworm to acoustic vibration at increasing frequencies?
- What is delayed auditory feedback, and why does it make a speaker stutter or fall silent?
- What is misophonia, and what sounds most commonly trigger it?
- What made real-time continuous speech recognition, which Raj Reddy pioneered at Carnegie Mellon, so difficult in the 1970s and 1980s?
- What question about animal vocalisation were researchers testing by putting a Chinese alligator in a helium-air mixture?
