Neural encoding of speech-in-noise in neonates: A frequency-following response study

Background noise disrupts the neural encoding of speech, making it particularly challenging to extract a speaker's voice from competing voices-an ability crucial for successful speech processing and communication. This disruption occurs across all ages, with infants and older adults being parti...
