The correct answer to this open question is the following.
Although you did not include options, we can say that one barrier to listening, emotional noise, involves the stress, anxiety, anger, or other emotion that interferes with our ability to give the speaker our full attention.
When we talk about emotional noise we refer to all those feelings and emotions and even thought that make you sad, impeding the consecution of things or the accomplishment of goals. Things such as worries, anxiety, doubt, or sadness are emotions that easily can sabotage your aspirations and make you feel down. That is why you have to pay attention to your thoughts and feelings, constantly.
