最近拿了个ER6i测了一下~

Etymotic ER6i is a in-the-ear type stereo headset. It provides a isolation of over 25dB against the noise outside. Below is the measurement done this morning in AE lab, CDC.

& k+ J0 m1 ~/ j+ e, x: f, GDue to the in-the-ear design, ER6i provides much better noise canceling compared with normal circumaural earphones and normal earbuds. In the frequency below 1 KHz, the isolation is around 18dB and more than 25dB over 1 KHz, as shown in the pictures above., O( T6 D) T' w0 O8 y8 ~1 I8 y4 A

Former try listening gives a feeling that the ER6i lacks in bass and it is proved by its response. Pictures below reveal why it’s bass-free.

The frequency response of ER6i conforms to the Type4.3 ear simulator well, which is shown as below. 3 f! K/ d- e+ A0 f2 O# v: c  N

Response of Bass-Rich ear bud (Brand Senmai)
( q% n* D5 i7 y7 E2 P* L! bCompared with the response given above, the ER6i’s response below 1 KHz is quite flat, within ±2dB. Instead, the Bass-Rich ear bud has a peak around 500Hz, which will result in plenty of bass elements while listening music. And that’s why ER6i is designed to classic music without too much bass.
" y1 A' @( T3 @$ TThe huge difference of THD may derive from driver type. ER6i applies balanced armature while the other dynamic.
