一 | The senator told the Greek news agency that the United States would sell military equipment to those who share its values, "not just for financial gain," and listed a number of problems on which Ankara should change its behavior and attitude. Among them are the issue of acquiring the Russia's S-400 system, flights over the Greek islands, Turkey's close relations with Russia, and human rights violations, including the imprisonment of journalists and lawyers.,Menendez added that the list of outstanding issues is long, and they must be resolved in order to achieve the sale and modernization of the F-16 jets, but he had not yet seen the readiness of Turkish President Recep Tayyip Erdogan to take any of these steps, the news agency reported.,Menendez is considered a person who "holds the keys to the F-16," since he has the power to veto the sale of the US weapons systems as the chairman of the Committee on Foreign Relations, the agency said.,Ankara Hopes for Success in F-16 Deal With US, Turkish Defence Minister Says10 May, 14:41 GMT,Turkey plans to purchase 40 F-16 fighter jets from the US, and modernize another 80 which it already has in service. US President Joe Biden said that he expects to obtain a congressional approval for the sale of the jets to Turkey, but a group of the US congressmen signed a statement objecting to the sale.。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。

三 | 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。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”。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。

四 | 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。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)。
