The QuickSIN is a speech-in-noise test that quickly and easily measures the ability to hear in noise. Speech understanding in noise cannot be reliably predicted from the pure tone audiogram or other standard audiometric tests. The QuickSIN test should be used on all adult patients as part of the audiometric test battery.

| Methodology |
QuickSIN MethodologyThe QuickSIN is comprised of sentences recorded in four-talker babble. It represents a realistic simulation of a social gathering, in which the listener may "tune out" the target talker and "tune in" one or more of the background talkers. Each of the twelve QuickSIN lists has six sentences, one sentence at each signal-to-noise ratio (SNR) of 25, 20, 15, 10, 5, and 0 dB. These SNRs encompass the range of normal to severely impaired performance in noise. Each sentence has five key words that are scored as correct/incorrect. A single QuickSIN list takes approximately one minute to administer and score. The QuickSIN manual contains reliability data based on the number of lists administered. Setup:
Testing:

| What is SNR Loss? |
SNR loss is the increased signal-to-noise ratio required by an individual to understand speech in noise, as compared to normal performance. A normal-hearing person requires about +2 dB SNR (target talker 2 dB louder than background babble talkers) to correctly repeat 50% of the key words on the QuickSIN test. We call this the SNR-50. A hearing-impaired person who requires the target speech to be 12 dB higher than the noise to achieve a 50% correct score would have a 10 dB SNR loss. QuickSIN scores are reported in SNR loss because it is substantially independent of calibration and test material. Calibration and/or test material differences that affect the SNR-50 values equally for normal and hearing-impaired subjects will "cancel out" in the SNR loss calculation. SNR Loss SolutionsHearing aids (regardless of the type of signal processing they use) cannot improve the SNR for the most commonly encountered difficult listening situation, i.e., when what the listener wants to hear is speech, and what the listener doesn't want to hear is also speech. SNR improvement can be provided by directional hearing aid microphones, array microphones, and FM systems. The QuickSIN test can be used to determine which, if any, of these technologies is appropriate for a given patient, as well as to counsel the patient regarding realistic expectations from a given technology. |

| Filtered Recordings |
High-Frequency Filtered (HFE) and Low-Pass (HFE-LP) ListsData on patients with ski-slope hearing loss indicate some of these individuals benefit from extended high frequency amplification (full bandwidth response), while others perform poorer with a full bandwidth response. HFE recordings
HFE-LP recordings
By comparing the results obtained with the HFE and HFE-LP lists, it may be possible to determine whether or not extended high frequency amplification is useful for an individual having a ski-slope hearing loss. When comparing HFE and HFE-LP conditions, administering two lists in each condition (four total) will provide a valid comparison to an accuracy of 1.8 dB at the 80% confidence level. For more detailed information, see the QuickSIN Manual. |

| CPT Codes |
CPT Codes for Speech-in-Noise TestsAt present, no CPT code exists for speech-in-noise tests. Practitioners who submit for reimbursement use CPT 92700 (Unlisted ENT Service or Procedure). Using this code requires a narrative describing the procedure and its purpose, as well as substantiation from the literature.
