Noise: sound that is usually loud that interrupts the communication process. When noise is present during the communication process, messages can be heard incorrectly or not at all, resulting in miscommunication. Examples of noise can be static on the phone, printers in the workplace, other people talking loudly around you, and music in the background (Weiner, 1990).
Nonverbal Communication: expressing ideas and messages without the use of spoken words. Nonverbal communication can be expressed with facial expressions, eye contact, touching (haptics), how you dress, and the distance between people. For example, if you are in a situation where you do not feel comfortable you can look at your friend and make an expression which would indicate that you want to leave immediately (fhsu.edu). Example of how facial expressions can tell us how a person is feeling without words.
Nonverbal Immediacy: expressing the liking or disliking of somebody through nonverbal cues. This is the idea that people shy away from those they do not like, while we try to spend more time with people we do like. Nonverbal cues that can show immediacy are eye contact, facial expressions, tone of voice, smiling, vocal pace, body tenseness, and limb movement (missouriwestern.edu).
Norms: rules that members of a group are expected to follow that are satisfactory to the other group members. For example, in a work group setting, it can be understood that nobody will discuss their personal life and only business. On the other hand, a group of friends could have the understanding that they can speak freely on whatever is on their mind (DeFleur, Kearney, Plax, & DeFleur, 2005).
