Currently various types of acoustic coupler has been specified and employed in measuring headphones and earphones. Because the tester used to select one of couplers by his/her preference, it was difficult to compare the characteristics of various headphones and earphones in a unified condition. For the signal source for the measurement, measuring method using a signal which includes wide range of frequency has not been proposed, and then it was difficult to evaluate headphones and earphones in a condition actually used by customer. On the other hand, a measuring method was proposed to use HATS as a unified measuring platform and to use a signal source similar to real sound program. However, because there were problems in the shape of the ear hole, the reproducibility of the measured result was poor. To solve these problems, I propose a good reproducible measuring method and platform with a new ear hole shape. |
