耳机不够。Bose为汽车引入了降噪技术_我的网站

一 |     Ever since Deepika Padukone exited Prabhas-starrer Spirit reportedly citing work shifts, the debate regarding professional work hours became the hottest topic in the film industry. The discussion about standardizing working hours – pushing for an 8-hour workday – has been ongoing. While actresses like Rashmika Mandanna have also weighed in supporting the need for healthier and regulated work hours, Keerthy Suresh is the latest actress to voice her opinion.               Keerthy gives a work shift breakdown     As part of promotions for her upcoming film Revolver Rita, Keerthy addressed the debated subject about an 8-hour workday in a press conference. She has made it clear and underlined that the thought of a “fixed shift” rarely reflects the reality of an actor’s life. “I do all kinds of shifts; 9 to 6, 9 to 9 and 9 to 2,” she commented. “While shooting for Mahanati, I have also shot for five other films. But I have also worked for films where the shooting was from 9 to 6.” The actress stated that while everyone discusses the 9–6 shift work hours, very few understand what actually happens behind the camera, and even the regular shifts are more demanding than it appears. Keerthy literally gives a breakdown on how work happens behind the camera. For me, I work both ways. In a 9-6 shift, I have to be ready with make-up on the set by 9; so I have to be on the sets by 7:30…means I have to leave at 6:30 for which I need to wake up at 5:30.          ‘Hardly get six hours of sleep’     Keerthy's statements underscore the persistent hierarchy of labour in the film industry. According to her, by the time actors complete work and return home, it’s already 10 PM. While everyone needs eight hours of sleep daily, Keerthy points out that it’s actually hard for actors to get that privilege during shoots. “What time do I have to wake up in the morning? At 5.30, we hardly get six hours of sleep, even when it's a 9-6 regular shift,” said Keerthy, who recently got married to boyfriend.     Also Read: Samantha Ruth Prabhu and Keerthy Suresh’s Meet Up Surprises Fans。1月10日，Bose希望将其备受赞誉的降噪技术从耳机到汽车。

二 | 这家总部位于马萨诸塞州弗里明翰的公司刚刚推出了一项名为“安静舒适”的新技术，该技术声称能够测量车辆振动以消除日常驾驶中的噪音。Bose指出，随着汽车的重量越来越轻，电动汽车越来越多，这种降噪技术可能会受到越来越多的关注。

三 | 坐在安静的电动汽车里的司机比坐在嘈杂的内燃机车更容易受到道路噪音的影响。Bose将这项技术定位为展望未来，因为道路上会有更多的电动汽车。那么它是如何工作的呢？传统的车辆降噪方法包括使用更厚的绝缘材料或专用轮胎，以尽量减少在崎岖不平的道路上行驶时产生的噪音。但这些方法增加了车辆重量，降低了燃油效率。Bose使用加速度计、专有的信号处理软件、麦克风和汽车内置音响系统的组合来“电子控制不需要的声音”。

四 | Bose说：安装在车身上的加速度计使Bose算法能够连续测量产生噪音的振动。然后，利用该信息计算出通过车辆扬声器传输的消声信号，以降低目标噪声。

五 | 放置在驾驶室中的麦克风监控残余噪音水平，允许系统调整控制信号以优化不同道路上的性能，并随车辆老化自动调整。虽然Bose有一个非常著名的降噪耳机，但它的车是一个非常不同和复杂的环境。

六 | 该公司指出，自2010年以来，其汽车部门已向汽车制造商提供了ehc，这是一项用于降低劣质发动机噪音的高目标技术。Bose表示，在降噪技术的发展过程中，将与汽车制造商合作，将该技术直接安装在汽车生产过程中，首批支持安静舒适的汽车将于2021年底投产。视频：（如果移动客户端用户无法观看视频，请单击此处查看）。
