这种频率属于极低频的频率范围内，通常极低频的频带范围也在300hz以下。

This falls in the extremely low frequency (ELF) range which includes frequencies up to 300 Hz.

众多研究表明，暴露在极低频率电磁场的儿童罹患白血病的风险增加，但极低频率电磁场似乎不增加乳腺癌和心血管疾病的发病风险。

Studies have consistently shown increasing risk for childhood leukemia associated with ELF-EMF, whereas ELF-EMF most likely are not a risking factor for breast cancer and cardiovascular disease.

谷歌的VR音频系统模拟这些闭塞效应治疗高和低频率成分不同，高频区被屏蔽比低频率。

The Google VR audio system simulates these occlusion effects by treating high and low frequency components differently, with high-frequencies being blocked more than low frequencies.

So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.

在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。
