title: [Measuring of spontaneous otoacoustic emissions of adolescence and its significance].
abstract: OBJECTIVE
  In order to study the relationship between spontaneous otoacoustic emissions (SOAE) and cochlear function.
  
  
  METHODS
  SOAE of 50 normal hearing young people were measured. The incidences, amplitudes and frequencies of SOAE were obtained.
  
  
  RESULTS
  The SOAE incidence was 40% in 100 ears of 50 cases and there was no significant difference in sexuality and laterality (P > 0.05); In the 40 cases who had SOAE, the amplitudes ranged from--27.5 dB SPL to 9.7 dB SPL and the frequencies ranged from 269 Hz to 5,660 Hz, without sexual difference; There is no significant difference between SOAE and threshold of pure tone acoustic (P > 0.05).
  
  
  CONCLUSIONS
  The appearance of SOAE indicated good cochlear function.
