Article: Contestants go through at least three sets of cuts. The first is a brief audition with a few other contestants in front of selectors which may include one of the show's producers. Although auditions can exceed 10,000 in each city, only a few hundred of these make it past the preliminary round of auditions. Successful contestants then sing in front of producers, where more may be cut. Only then can they proceed to audition in front of the judges, which is the only audition stage shown on television. Those selected by the judges are sent to Hollywood. Between 1060 people in each city may make it to Hollywood[citation needed].

Question: What is the only televised portion of the preliminary audition rounds?
Ans: in front of the judges

Article: Delicate sounds and fine overtones were mostly lost, because it took a lot of sound energy to vibrate the recording horn diaphragm and cutting mechanism. There were acoustic limitations due to mechanical resonances in both the recording and playback system. Some pictures of acoustic recording sessions show horns wrapped with tape to help mute these resonances. Even an acoustic recording played back electrically on modern equipment sounds like it was recorded through a horn, notwithstanding a reduction in distortion because of the modern playback. Toward the end of the acoustic era, there were many fine examples of recordings made with horns.

Question: What was the cause of delicate and fine sound loss?
Ans: took a lot of sound energy

Article: Northwestern was elected to the Association of American Universities in 1917 and remains a research university with "very high" research activity. Northwestern's schools of management, engineering, and communication are among the most academically productive in the nation. Northwestern received $550 million in research funding in 2014. Northwestern supports nearly 1,500 research laboratories across two campuses, predominately in the medical and biological sciences. Through the Innovation and New Ventures Office (INVO), Northwestern researchers disclosed 247 inventions, filed 270 patents applications, received 81 foreign and US patents, started 12 companies, and generated $79.8 million in licensing revenue in 2013. The bulk of revenue has come from a patent on pregabalin, a synthesized organic molecule discovered by chemistry professor Richard Silverman, which ultimately was marketed as Lyrica, a drug sold by Pfizer, to combat epilepsy, neuropathic pain, and fibromyalgia. INVO has been involved in creating a number of centers, including the Center for Developmental Therapeutics (CDT) and the Center for Device Development (CD2). It has also helped form over 50 Northwestern startup companies based on Northwestern technologies.

Question: Which of Northwestern's schools are among the most academically productive in the nation?
Ans: management, engineering, and communication
