tzs: > Hearing aids typically cost anywhere from ₹ 50,000 to upwards of ₹ 8L depending on the correction capabilityFor those who don't recognize the ₹ symbol it is the symbol for the Indian Rupee and an "L" after a number means 100,000, so ₹ 8L is ₹ 800,000.At current exchange rates that puts hearing aids in India from $600 to upwards of $9,500.AirPods Pro 2 are ₹ 24,900 ($295).

tzs: &gt；助听器的价格通常从50000卢比到8L不等，具体取决于矫正能力；我不认识₹符号，它是印度卢比的符号和&quot；L&quot；后面的数字意味着100000，所以8L是800000。按照目前的汇率，印度的助听器从600美元到9500美元以上。AirPods Pro 2是24900卢比（295美元）。

userbinator: It appears that the Hearing Aid feature is actually an equalizer preset that is pushed to the AirPods and will replace your transparency mode.Apple could've just not marketed these as "hearing aids" or used the medical terminology, as every other TWS with parametric EQ and transparency mode can do the same thing, and they wouldn't have the regulatory hawks going after them. They only lose the marketing edge, but perhaps that was a huge calculated risk.There's an incredible amount of processing power and flexibility in these things. Even the sub-$10 ones using the infamous JieLi SoCs - a 160MHz 32-bit computer in each ear. I'm surprised there hasn't yet been any TWS advertised with open-source firmware, although there's been some work in the usual Chinese (and Russian) communities on customisations.

userbinator: 看起来助听器功能实际上是一个均衡器预设，它被推送到AirPods上，将取代你的透明度模式 苹果可以；我只是没有把这些作为“；助听器&quot；或者使用医学术语，因为具有参数EQ和透明度模式的所有其他TWS都可以做同样的事情，而且它们不会；不要让监管鹰派追捕他们。他们只会失去营销优势，但也许这是一个巨大的风险 那里；这些东西具有令人难以置信的处理能力和灵活性。即使是那些使用臭名昭著的洁利SoC（每只耳朵都有一台160MHz的32位计算机）的10美元以下的电脑。我；我很惊讶没有；还没有任何TWS用开源固件做广告，尽管有；在通常的中国（和俄罗斯）社区，定制方面做了一些工作。

post_break: Does this reset itself after a certain amount of time or is it one and done? I'd be worried about the feature being removed when the iPad or airpods decide they've been in India for too long.

post_break: 这是在一定时间后自动重置，还是一次性重置？我；当iPad或airpods决定删除该功能时，我会担心它会被删除；我在印度待得太久了。

myself248: This is fantastic! We're building a walk-in-closet-sized Faraday cage at i3Detroit, though of course we're in the US so we won't need it for this specific hack, there's a zillion reasons it's fun to have one!Off the top of my head:The biggie is that we're right down the street from WOMC's transmitter, which is 135,000 watts EIRP. It gets into EVERYTHING and makes other RF measurements more difficult, so if you're trying to align an amplifier or something, it's nice to start from a quiet place and get the basics solid, and only THEN add sources of potential intermod and stuff.Debugging wifi, bluetooth, and other wireless stuff without a zillion other nodes in view. Yes you can filter the output of a sniffer, but it's more fun to filter the input. ;)Lighting up a 1G or 2G cellular network without worrying about spectrum licensing.Practicing offensive wifi techniques or other stuff that might interfere with the hackerspace's existing network.Playing with GPS spoofers in an FCC-free zone. Or anything else you might find amusing but want to do responsibly.Locking an iPhone in there to see if it reboots itself... (rofl)

myself248: 这太棒了！我们；在i3Detroit重建一个步入式壁橱大小的法拉第笼，当然我们；我们在美国，所以我们赢了；对于这个特定的黑客攻击不需要它，有；这有无数的理由；有一个很有趣 我突然想到：重要的是我们；就在WOMC街的正对面；s发射机，功率为135000瓦EIRP。它会进入一切，使其他RF测量变得更加困难，所以如果你；如果你试图对准放大器或其他东西，它；从一个安静的地方开始，扎实地掌握基础知识，然后才能增加潜在的食物和东西的来源，这很好 在没有无数其他节点的情况下调试wifi、蓝牙和其他无线设备。是的，您可以过滤嗅探器的输出，但它；过滤输入更有趣。；） 点亮1G或2G蜂窝网络，无需担心频谱许可 练习攻击性wifi技术或其他可能干扰黑客空间的东西；在FCC自由区玩GPS骗子。或者任何你可能觉得有趣但想负责任地做的事情 将iPhone锁定在那里，看看它是否会自动重启。。。（rofl）
