描述了一种灵敏的、自平衡的噪声测量设备，称为声速计。该仪器是为IGY期间电离层吸收的常规测量而设计的，使用宇宙噪声法。这项技术在极光带的应用已经导致电离层吸收的定量测量，即使在极地停电期间。与简单的全功率宇宙噪声接收系统相比，该系统具有以下优点：1)对输入噪声功率的变化具有线性响应；2)在窄带射频干扰下具有较高的精度；3)长期稳定性好。
A sensitive, self-balancing, noise-measuring equipment, known as the riometer, is described. This instrument has been designed for routine measurement of ionospheric absorption during the IGY, using the cosmic noise method. Application of this technique in the auroral zone has resulted in quantitative measurements of ionospheric absorption, even during polar blackouts. The riometer has the advantages over a simple total-power cosmic noise receiving system of 1) linear response to changes of input noise power, 2) high accuracy in the presence of narrow-band RF interference, and 3) good long-term stability.
