Objective:
To study the voice characteristics and differences of normal people with different sexes and ages, and to analyze the related factors, adopt suitable acoustic parameter values.
Method:
To collect and analyze acoustic parameter values of 1200 normal people who were divided by sex (male and female) and age (group 1: before puberty; group 2: after puberty to 30; group 3: 31 to 45; group 4: 46 to 60; 5: 61 and older), laryngeal manifestations of different sex and age under stroboscopy were analyzed.
Result:
Acoustic parameters of men and women have different characteristics. (1) F0, jitter, NNE of women voice are significantly higher than men. (2) Voice amplitude, MPT and formant frequencies of men are significantly higher than those of women. (3) Male and female voice characteristics and anatomic and physiological mechanisms of different age--groups are different.
Conclusion:
Acoustic parameters of normal people with different sexes and ages have different characteristics, which are related to anatomic and physiological mechanisms and other factors.
