Auditory sense training method and sound processing method for auditory sense training

Abstract

An auditory sense training device 1 to be used in an auditory sense training method for training auditory sense by listening to a sound formed by processing an original sound comprises a band attenuation processing method 20 for attenuating a predetermined frequency band of an original sound 10, a switching means 30 for selectively outputting either the original sound or the output from said band attenuation processing means, a panpot processing means 40 for performing a panpot process wherein a voice signal formed by attenuating an original sound of one channel is superposed to the original sound of another channel, and a phase reverse processing means 50 for performing a phase reverse process of reversing the phase of the original sound, wherein a trainee listens to the original sound and a band attenuation processed sound formed by attenuating a predetermined frequency band of the original sound alternately.

1 . An auditory sense training method for training the auditory sense of a trainee, the method comprising: 
 having the trainee listen to a sound formed in part by processing an original sound to form a phase reverse processed sound that is formed by a phase reverse process performed on said original sound for roughly reversing the phase of the original sound,    wherein said original sound and the phase reverse processed sound are listened to alternately by said trainee.    
   
   
       2 . An auditory sense training method according to  claim 1 , wherein the processing time of said phase reverse process is set randomly and arranged in time order.  
   
   
       3 . A sound processing method for auditory sense training of a trainee, the method comprising: 
 having the trainee listen to a sound of channels formed by sound processing an original sound,    wherein said sound processing includes attenuating the amplitude of the original sound of a first channel and superposing the attenuated sound of the first channel onto the original sound of a second channel.    
   
   
       4 . A sound processing method for auditory sense training disclosed in  claim 3 , wherein the processed sound performed of said process is outputted alternately with a sound not being performed of said process.  
   
   
       5 . The sound processing method for auditory sense training disclosed in  claim 3 , wherein said process is characterized in that the sum of said amplitude attenuation processed sound outputted to said one channel and said amplitude attenuation processed sound outputted to said other channel is fixed for one channel signal.  
   
   
       6 . The sound processing method for auditory sense training disclosed in  claim 3 , wherein said process is performed by a plurality of various process patterns.  
   
   
       7 . A sound processing method for auditory sense training of a trainee, the method comprising: 
 having the trainee listen to a sound formed by processing an original sound,    wherein a phase reverse process for reversing the phase of the original sound is performed on said original sound.    
   
   
       8 . The sound processing method for auditory sense training according to  claim 7 , wherein the processing time of said phase reverse process is set randomly.  
   
   
       9 . The sound processing method for auditory sense training according to  claim 3 , wherein said process patterns and the processing time being set randomly and arranged in time order.  
   
   
       10 . The sound processing method for auditory sense training according to  claim 3 , wherein said region attenuation processed sound has a duration between 0.1 seconds and 7 seconds.
