Input: Read this: 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: Why do photos show take on horns?

Output: help mute these resonances

IBM was among the first corporations to provide group life insurance (1934), survivor benefits (1935) and paid vacations (1937). In 1932 IBM created an Education Department to oversee training for employees, which oversaw the completion of the IBM Schoolhouse at Endicott in 1933. In 1935, the employee magazine Think was created. Also that year, IBM held its first training class for female systems service professionals. In 1942, IBM launched a program to train and employ disabled people in Topeka, Kansas. The next year classes began in New York City, and soon the company was asked to join the President's Committee for Employment of the Handicapped. In 1946, the company hired its first black salesman, 18 years before the Civil Rights Act of 1964. In 1947, IBM announced a Total and Permanent Disability Income Plan for employees. A vested rights pension was added to the IBM retirement plan. During IBM's management transformation in the 1990s revisions were made to these pension plans to reduce IBM's pension liabilities.
