Present list pairs from the standard CD through a loudspeaker in the sound field around 45dB. It is a speech-in-noise test that uses sentences recorded in four-talker babble. This test helps estimates SNR loss in children and adults. SNR loss is the increased signal-to-noise ratio required by a listener to understand speech in noise compared to normal speech. The BKB-SIN contains 18 list pairs that differ by difficulty, and each list pair has two lists. Both lists of the pair must be administered, and the scores are averaged for validity. Once the results are found, they are then compared to normative data to obtain the SNR loss. List pairs 1-8 have ten sentences in each list, with one sentence at each SNR of +21, +18, +15, +12, +9, +6, +3, 0, -3, and -6 dB. List pairs 9-18 have eight sentences in each list, with one sentence at each SNR of: +21, +18, +15, +12, +9, +6, +3, and 0 dB.

These key words are underlined in the score sheets. Each key word repeated correctly is one point. Subtract the total correct from each list from 23.5 to get the SNR-50; this is the signal-to-noise ratio for 50% correct. The next step is to average the SNR-50 scores for both lists of the list pair, then average the list pair scores. Finally, compare the list pair score to the age-related norm to determine the SNR loss.

1. What questions (hypotheses) are addressed in the paper? Look in the Abstract. Can we calculate the equilibrium for the entire MgO-SiO2 range? If so, can we use these values to create a phase diagram for these minerals? What minerals are present in this composition range? 2. What are the main conclusions of the paper? Look in the Abstract and Conclusions. The main conclusions of the paper are that the most accurate part of the MgO-SiO2 range to calculate equilibrium is the middle compositions…

It causes the bext axon to open up its gates 5. What is the role of the voltage-gated sodium channels for producing an action potential? The gated channels allow the sodium into the axon which causes the membrane potential above the threshold 6. What is the role of the voltage-gated potassium channels? Potassium gates close after sodium gates close too 7. What would happen if the voltage gated sodium and potassium channels opened a. at the same…

three quarters did not like the outside preparation. The one quarter liked the outside preparation because they felt that the research gave them more background about the lab they were doing. They could spend the time researching online exactly what the experiment wanted us to do. The other three quarters of the group felt that the labs were too difficult, and that the descriptions on canvas didn't provide enough information to create a procedure. They would prefer to have a procedure given to them. New…

The balance of protons and neutrons in a nucleus determines whether it will be stable or unstable. If the nucleus has too many protons or too many neutrons this will upset the balance. The upset of the balance disrupts the strong nuclear forces and the nucleus becomes unstable. The graph below demonstrates the neutron to proton ratio: From the graph shown many stable nuclei have an equal number of protons to neutrons, these are elements in the lighter sections of the periodic table. The heavier…

block is initially at rest. The bullet is traveling 300 m/s when it hits the wood block and sticks inside it. Now the bullet and the wood block move together as one object. How fast are they traveling? 0.04(300) =0.5+0.04v 12=0.24v V=22.22m/s 6. Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who has a mass of 40 kg, is traveling in the opposite direction at 5 m/s. They crash into each other and hold onto each other so that they move as one mass…
