11. This has led the town to develop a noise reduction plan. 12. These boats are quieter, with more advanced electronics, sensors, and noise reduction technology. 13. Some shooters use both simultaneously to gain greater noise reduction ( NRR ). 14. Lip-ribbon microphones are more efficient at noise reduction at lower frequencies. 15. Different algorithms for noise reduction control these artifacts with varying levels of success. 16. The Bose QuietComfort is particularly effective and offers two levels of noise reduction . 17. They also provide security and noise reduction at the touch of a button. 18. In 1964 Philips launched the Compact Cassette, and in 1965 Dolby noise reduction . 19. It includes a dual auto-reverse cassette deck that uses Dolby B noise reduction . 20. Techniques of noise reduction are usually applied prior to the calculation.
