The word “Signal” is derived from the Latin word “signum”, which means a mark or sign. It is simply means transmitting information using different ways. Signal Communication is the method or means of conveying information of any kind from one person or place to another.

The Means of Communication is the medium by which a message is conveyed from one person or place to another Agency of Communication is a facility which embraces the personnel and equipment necessary to provide signal communication by any particular means.Actually, these signals are very important for communication in business. There are two kinds of signals; Voice is a direct communications between two or more individuals. It is the most common method available to the user and it includes telephone, voice radio and radio wire integration. There is a big importance of human visual signals in human collaboration. Also, Visual signals include, among other things, gesture, facial expression, and direction of gaze.

Shannon and Weaver are considered one of the most important seeds from which communication theory has grown.They described communication as a simple, linear process of sending a signal from sender to receiver. The focus is on the precision and efficiency of communication. The aim of this article is to investigate how audio and visual signals are important to in communication in business and industry. Syahirah Hasifah, said, "People tend to eye-minded, and the impacts visual aids bring to a presentation are, indeed, significant” “With pictures, the concepts or ideas you present are no longer simply words- but words plus images” Nature and Purpose of Audio and Visual Aids Being memorable.Body paragraphs: Audio and visual aids in business communication and training help in numerous ways.

Each individual understands and retains information differently, which is why professional training organizations use multiple audio and visual tools during presentation sessions. This type of session is commonly known as a "multimedia presentation," which can include written, visual, auditory and sometimes interactive methods. Using visual aids can save business time, especially if the subject contains information that may be too long for written or oral communication.Pie charts, graphs, diagrams, photographs, video shorts and animation can often help explain subject matter quickly, and in a manner that is more easily absorbed by the learner. Time is valuable in every organization, so the importance of timely and effective implementation of training and communication should be a prime consideration.

Visual aids can include projectors, flip charts, models, white boards or any combination thereof. The type of auditory aid used in multimedia presentation is most likely based on budget, but the effectiveness of each type must be considered.Live speakers that are experienced in adult learning concepts and have working knowledge of the subject, offer an interactive experience. If a point or concept is not clear, the trainer is present to answer questions and go into further detail. Live trainers also serve to add personality to the program, and can provide individual attention to persons or groups if needed. Prerecorded voices used in presentations may seem cost-effective and get the job done, but there is no guarantee that the communication was fully understood.

Handouts serve to reinforce oral and visual components, and can go into further detail if desired or warranted.Handouts allow participants to follow along with presented information, make notes, formulate questions or refer to key points in the future as a "refresher course. " For individuals who learn more effectively by reading than other means, handouts are an important part of business training and communication. Adding short quizzes and "fill in the blank" sections to handouts helps reinforce to material, and engages the participants in the process.

Using multiple mediums during presentations can help individuals and groups to interact and become part of the session.Persons who are engaged in the process tend to retain and understand information more effectively, and are less prone to inattentiveness. Participation in games sessions, team and whole-group activities not only breaks up the monotony, but encourages and reinforces learning, management and team building skills. Employees that are engaged in the process of business training and communication are better equipped to put information to use in real-life business situations.

Business communication needs visual elements in order to be effective.When used correctly, photographs and videos can enhance understanding and message retention. Communication professional Ellen Coomber writes in "The Visual Advantage" that "words alone are not enough to deal with today's complex business problems. " In a society used to visual stimulation and pressed for time, graphics become an important form of communication for businesses. Advantages of visual communication • Visual communications differentiate one business from another.

Photos and the like organize complex information into a quick, easy-to-understand form.The visual can also grab the target audience's attention. Communication researchers at the University of Lugano, Switzerland, Jeanne Mengis and Martin Eppler write of the "familiar surprise" in their article "Be Heard, Understood and Remembered in an Overloaded Environment. " A graphic with recognizable elements used in new ways will create curiosity and stimulate interest in the business. Disadvantages of visual communication • Graphic design, videos and photography are often expensive and time consuming.

Visual communication at any complex level requires specialized skills.Distribution problems can occur with visuals in that every audience member must be able to download, view, or obtain the graphics, often with different equipment. In this sense, visuals must be user-friendly and distribution must be thought through carefully. When to use visual communication Businesses should use graphic elements in communication to aid understanding. According to Jeanne Mengis and Martin Eppler, "The more complex, uncertain, ambiguous, diverse and novel information is, the quicker people feel overwhelmed and lose their ability to effectively absorb and use the information.

It is important to keep visuals simple and easy to decipher.Do not use visuals just to make the communication pretty. Brian O'Mara-Croft writes in his article "Every Picture Tells a Story" that "this is about real means to real results, not window dressing designed to evade legitimate problems. A picture is only worth a thousand words if the message is accurate, relevant and well constructed.

" Here are some types of visual signals; Imagery such as photos and illustrations can show the reality of a business situation or message.To be done effectively, a skilled photographer, illustrator or other professional is necessary. Typography is used when designing textual elements. Graphic designers typically use computer programs to lay out text in a way that will aid the audience's understanding of the message. It must be easy-to-read, but the textual design can impart information beyond the words on the page.

Finally, video is useful for more complex explanations or information. Ellen Coomber suggests using "meaningful titles to draw the viewer in and summarize the information presented. Use business branding throughout the communication piece to reinforce the visual elements with the specific business. Brian O'Mara-Croft, owner of Visual Congruence, advises that businesses use the familiar and focus on the big picture. This requires target audience research, and designs that incorporate communication objectives.

ConclusionIn conclusion, visual and audio signals are very important in business communication, so it guarantee the best results in the world of business. Although it is so useful and beneficial, it should be used correctly to take the advantages and the best effect.
