Rems

Question 1

REUR

Answer 1

Real ear unaided response. The SPL, across frequencies measured in the open unaided ear canal for a given input signal.

Question 2

REUG

Answer 2

Real ear unaided gain. The input signal (pure tone) subtracted from REUR is the REUG.

Question 3

REIG

Answer 3

Real ear insertion gain. The difference between aided and unaided ear canal SPL (REAR-REUR=REIG). REIG Is a calculated difference measurements

Question 4

REOG

Answer 4

Real ear occluded gain. The difference in db, across frequencies, between the signal level measured in the ear canal and the input signal, with the aid turned off.

Question 5

REAR

Answer 5

Real ear aided response. The output of a hearing aid that is turned on, measured at the TM.

Question 6

REAG

Answer 6

Real ear aided gain. The gain across frequencies of a hearing aid that is turned on, measured at the eardrum. The input signal subtracted from the REAR is REAG.

Question 7

RECD

Answer 7

Real ear to coupler difference. Difference in dB across frequencies, between the SPL measured in the ear at the TM and in a 2cc coupler, produced by a transducer generating the same input signal

Question 8

What is real ear measurements

Answer 8

Rems is the measurement made using a test box or rem device. It can measure the reference microphone at the canal entrance and the probe microphone deep in the canal.

Question 9

What can rems be used for and why?

Answer 9

Helps to overcome differences such as types of aids prescribed, patients unique ear canal acoustics and the method in which the hearing aid is passing sound into the ear by objectively measuring and verifying the sound that is being delivered to the TM.

Question 10

Benefits of REMS

Answer 10

Can be applied at initial fitting and at service appointments - gains better patient satisfaction = less follow ups

Question 11

Placement of REM equipment

Answer 11

Loudspeaker approx 0.5-1m away from listener.
Quiet room
No hard reflective surfaces
Clinician out of immediate acoustics space beside ear

Question 12

Advantages of REMS

Answer 12

-Objective measurement of real ear hearing aid performance
-can be used with patient who can’t perform behavioural tests
-quick, valid and reliable test of aid performance
-accurate modification of frequency response of hearing aid

Question 13

Disadvantages of REMS

Answer 13

-placement of prove can be difficult and requires practice
- probe tube can affect low frequency response
- placement of probe can cause acoustic feedback
- cannot be used with a perforated ear drum or a mastoid cavity

Question 14

What is speech mapping?

Answer 14

It is a fitting verification method that ensures that your hearing aids can be set according to your needs.

Question 15

Benefits of speech mapping

Answer 15

Focuses on hearing speech and sounds
Immediate results
Increased confidence using new aids
Accuracy
Exactly maps your aids at first try
