The Speech-in-Noise exercise constitutes approximately 30% of the total adaptive training. Training is organized into topics (health issues, money matters, exercise, etc.) that are selected by the trainee at the beginning of the training session in order to reinforce the importance of utilizing contextual cues by keeping the general topic in mind when listening. This task consists of sentences presented in the presence of multi-talker babble. Initially, the signal-to-noise ratio (SNR) is +10 dB. The trainee repeats as much of the sentence as he or she comprehends, either aloud or silently. The subject then progresses to the next screen where the sentence is presented visually.

Examples are for demonstration purposes only. LACE adapts to your listening threshold so the exercises should never be too easy or too difficult.
The trainee is then asked to determine whether he or she understood every word in the sentence, and to confirm by selecting “yes” or “no.” The sentence is then presented again to the trainee in both the visual and auditory mode. If the “yes” button was selected, the next sentence is presented at the same intensity level, but the noise level is increased by 4 dB, thus yielding a +6 dB SNR. Alternately, if the trainee responded that he or she did not fully comprehend the sentence, the next presentation will be at a +14 dB SNR. The training continues in this manner for five presentations, after which the step size for altering the SNR is reduced to 2 dB. At the start of the next SB training session, the SNR is presented at two steps (4 dB SNR) above the average performance of the previous training session, and all step sizes thereafter are 2 dB.
QuickSIN™ Speech-in-Noise Test
Included in LACE for no additional fee is the QuickSIN which 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.

LACE encouraged me to try harder and as a result I learned where my weaknesses are and how to help strengthen those weaknesses. The program is easy to use and does not take a lot of time each day so you don’t mind following through with the training. I think I am a better listener now.
I found the program very useful and noticed a marked improvement in my listening over time. I also experienced a leap in confidence in all my social listening. I also noticed that I often did not understand the first time something was played but that it became easier with repetition. I liked being able to playback what I heard and found this very helpful as things began to become clearer the more I listened.
I completed the training and I am very happy with the results. I feel so inspired, and grateful to understand the process of learning to hear with the brain. Thank you, The LACE Company, for giving me back my Youth and Joy of enjoying my many lectures, family, friends and group meetings.
Thanks for the opportunity to get practice and feedback in improving my ability to hear! I have been in a number of situations since I began my training that I am sure I would not have been able to understand what was going on before I had the training!
Thanks so much for this great program! I feel that many of the tasks have assisted me in learning to actively listen to those speakers around me no matter what the listening environment presents. LACE is an extremely effective way to increase one’s listening skills over time!
I have had a hearing loss since birth, but it was only detected at the age of 45. The LACE program has taught me the importance of paying attention and helping to block out background noises. I would highly recommend it!
