What are noise canceling headphones?

Noise-canceling headphones reduce ambient noise so the user can enjoy a greater degree of silence to relax or listen to music at a lower volume than would otherwise be necessary. By removing competing noises from the acoustic surround, noise-cancelling headphones create a more easurable listening experience, do noise cancelling headphones block out construction noise. There are two main types of noise cancellation: passive and active.

High frequencies in the immediate environment can be largely blocked by the use of dense materials in the construction of the earphones. This is known as passive noise cancellation (PNC) and is especially effective on models with larger headphones. The downside is that PNC doesn't lend itself to lightweight headphones or in-ear headphones that sit at the open end of the ear canal. In-the-ear headphones, however, slip comfortably into the ear and block high-frequency noise more effectively.

To block out lower frequencies, noise-cancelling headphones emoy built-in electronics that continuously same ambient noise and generate reverse sound waves through the earpiece to accurately cancel out the ambient footprint. To accomish this, a small microphone built into the earpiece feeds the surrounding noise into the electronics, whi generates an opposing waveform and sends it through the earpieces. This is known as Active Noise Cancellation (ANC) and requires power via a reargeable battery.

The most effective noise-cancelling headphones use ANC to cancel low frequencies and PNC to cancel high frequencies. Exames of the former might be the hum of a refrigerator motor, an air conditioning unit, the subway, or airline engines. In the latter case, it was on a ane that Amar Bose, founder of the Bose Corporation, first conceived of noise-cancelling headphones, as the airline's headphones were drowned out by the ane's engines. His idea was soon followed by others, and today there is no shortage of models to oose from.

Like any other tenology, ANC and PNC have their limitations. ANC works best at reducing background noises that are constant, rather than the constantly anging noises of nearby atter or the cacophony of general hustle and bustle. Also, peoe who find in-canal headphones uncomfortable and prefer lightweight headphones may find effective noise-canceling headphones a bit expensive. Generally, it's eaper and easier to build a heavier, bulkier mug.

All things considered, noise-cancelling headphones can be of great benefit to the wearer in the right situations. Whether a person wants to block out the neighbor's garden crew drone for a nap or listen to their favorite soft music on a long flight from coast to coast, noise-cancelling headphones could be a good solution to noise problems..

Расчет высокопрочных болтов на растяжение

Особенности расчета на прочность элементов, ослабленных отверстиями под высокопрочные болты:
При статической нагрузке, если ослабление менее 15 °/о, расчет ведется по площади брутто А, а если ослабление больше 15 %—по условной площади Лусл = 1,18 Ап.

Монтажные стыки

Монтажные стыки делают при невозможности транспортирования элементов в целом виде.
Монтажные стыки для удобства сборки устраивают универсальными: все прокатные элементы балки соединяют в одном сечении.

Проверка прочности

Проверка прочности сечения на опоре балки по касательным напряжениям:
Балочной клеткой называется система перекрестных балок, предназначенная для опирания настила при устройстве перекрытия над какой-либо площадью.
