Which type of quantization is most preferable for audio signals for a

1.	Which type of quantization is most preferable for audio signals for a human ear?(a) Uniform quantization(b) Non uniform quantization(c) Uniform & Non uniform quantization(d) None of the mentionedThis question was addressed to me during an online exam.I would like to ask this question from Uniform and Non Uniform Quantization in division Formatting and Baseband Modulation of Digital Communications
Answer» Correct option is (b) NON uniform quantization The explanation is: The HUMAN ear is sensitive to quantization error in SMALL VALUES so non uniform quantization is more preferable than uniform quantization.
