Audio Frequency Analysis in Mobile Phones
Aguilar, Horacio Munguía
Physics Education, v51 n1 Article 015003 Jan 2016
A new experiment using mobile phones is proposed in which its audio frequency response is analyzed using the audio port for inputting external signal and getting a measurable output. This experiment shows how the limited audio bandwidth used in mobile telephony is the main cause of the poor speech quality in this service. A brief discussion is given about the relationship between voice bandwidth and voice quality.
