Environmental and Physical Barriers to Listening

Environmental factors such as lighting, temperature, and furniture affect our ability to listen. A room that is too dark can make us sleepy, just as a room that is too warm or cool can raise awareness of our physical discomfort to a point that it is distracting. Some seating arrangements facilitate listening, while others separate people. In general, listening is easier when listeners can make direct eye contact with and are in close physical proximity to a speaker. You may recall from Chapter 4 "Nonverbal Communication" that when group members are allowed to choose a leader, they often choose the person who is sitting at the center or head of the table.Peter A. Andersen, Nonverbal Communication: Forms and Functions (Mountain View, CA: Mayfield, 1999), 57–58. Even though the person may not have demonstrated any leadership abilities, people subconsciously gravitate toward speakers that are nonverbally accessible. The ability to effectively see and hear a person increases people’s confidence in their abilities to receive and process information. Eye contact and physical proximity can still be affected by noise. As we learned in Chapter 1 "Introduction to Communication Studies", environmental noises such as a whirring air conditioner, barking dogs, or a ringing fire alarm can obviously interfere with listening despite direct lines of sight and well-placed furniture.

Physiological noise, like environmental noise, can interfere with our ability to process incoming information. This is considered a physical barrier to effective listening because it emanates from our physical body. Physiological noise is noise stemming from a physical illness, injury, or bodily stress. Ailments such as a cold, a broken leg, a headache, or a poison ivy outbreak can range from annoying to unbearably painful and impact our listening relative to their intensity. Another type of noise, psychological noise, bridges physical and cognitive barriers to effective listening. Psychological noise, or noise stemming from our psychological states including moods and level of arousal, can facilitate or impede listening. Any mood or state of arousal, positive or negative, that is too far above or below our regular baseline creates a barrier to message reception and processing. The generally positive emotional state of being in love can be just as much of a barrier as feeling hatred. Excited arousal can also distract as much as anxious arousal. Stress about an upcoming events ranging from losing a job, to having surgery, to wondering about what to eat for lunch can overshadow incoming messages. While we will explore cognitive barriers to effective listening more in the next section, psychological noise is relevant here given that the body and mind are not completely separate. In fact, they can interact in ways that further interfere with listening. Fatigue, for example, is usually a combination of psychological and physiological stresses that manifests as stress (psychological noise) and weakness, sleepiness, and tiredness (physiological noise). Additionally, mental anxiety (psychological noise) can also manifest itself in our bodies through trembling, sweating, blushing, or even breaking out in rashes (physiological noise).
