The type of interference that comes from devices that radiate energy is known as?

Radio frequency interference refers specifically to the disruption or degradation of a signal due to other signals emitted in the radio frequency spectrum. This type of interference often occurs when electronic devices, such as radios, televisions, and various wireless communication systems, emit signals that can overlap with or disrupt the intended communication signals.

The phenomenon is primarily a concern in wireless communication, where devices like wireless routers, smartphones, and other RF-emitting apparatus can unintentionally interfere with each other's operations, leading to diminished performance or clarity in communication. Understanding this interference is crucial for optimizing communication systems and ensuring reliable wireless operations.

In contrast, electromagnetic interference encompasses a broader range of disturbances that affect signals through various electromagnetic emissions, not strictly limited to radio frequencies. Signal degradation pertains to the loss of signal quality, which may result from various factors, and acoustic interference involves sound waves, not electromagnetic signals.
