Q

CAMEQ2-HF/ CAM2 - Cambridge loudness equalization high frequency

A

A non-linear prescription that equalizes loudness using thresholds up to 10 kHz

17
Q

NAL - National acoustic laboratories of Australia

A

A linear prescription aimed to maximize speech intelligibility at the listening level preferred by the aid wearer. Based on thresholds and the half gain rule

18
Q

NAL - NL 1 & 2

A

A non-linear prescription aimed to maximize speech intelligibility based on thresholds. Takes into account dead zones

19
Q

DSL - Desired sensation level

A

A linear prescription that provides an audible comfortable signal at each frequency region. Uses REAR

20
Q

DSL[i/o]

A

Non- linear prescriptions that normalize loudness across frequencies. They are based on both loudness and thresholds.

DSL[i/o] - linear uses WDRC
DSL[i/o] - Curvilinear normalizes loudness

21
Q

DSLm[i/o] - Multistage

A

Limits at the highest levels
WDRC at mid-levels
Linear amplification below compression thresholds (optional expansion)

22
Q

NAL vs. DSL (non- linear prescriptions)

Fundamental principle

A

NAL maximizes speech intelligibility

DSL is a threshold based loudness normalization prescription, maximizing audibility

23
Q

NAL Vs. DSL (non-linear prescriptions)

Over all average gain

A

NAL prescribes less average gain over all

DSL prescribes higher average gain, more than is preferred by adults

24
Q

NAL Vs. DSL (non-linear prescriptions)

Language

A

NAL takes into account patients that speak tonal languages

DSL does not take this into account

25
Q

NAL Vs. DSL (non-linear prescriptions)

Compression

A

NAL - The compression threshold prescribed is based on speech at an overall level of 52 dB SPL

DSL[i/o]- linear –prescribes a greater compression ratio than that required to normalize loudness. DSL uses low compression thresholds so that all speech can be within compression region

26
Q

NAL Vs. DSL (non-linear prescriptions)

Dead regions

A

NAL takes into account dead regions, does not amplify much in that region since the is little benefit

DSL does not take dead regions into account

27
Q

NAL Vs. DSL (non-linear prescriptions)

Maximum Power Output (MPO)

A

NAL finds the LDL based on the threshold, and the point at which speech starts to clip. MPO is placed between these two levels

DSL takes into account loudness summation across frequency and the crest factor of speech is specified for broadband signals

28
Q

NAL Vs. DSL (non-linear prescriptions)

User experience

A

NAL takes into account new users vs. experienced users

DSL does not offer a correction for user experience

29
Q

NAL Vs. DSL (non-linear prescriptions)

Gender Differences

A

NAL takes gender into account, males get more gain than females

DSL does not take gender into account

30
Q

NAL Vs. DSL (non-linear prescriptions)

LDL

A

NAL does not allow patient specific information to be enter to change he LDL

DSL allows the audiologist to enter patient specific loudness discomfort levels
