When utilizing digital technologies today, more clarity is being created for the user. Mentioning digital transcription equipment is a good example to start off with. First look at what purpose transcription equipment was originally intended. Then have a look at what digitally powered transcription devices enable its users to do today. Transcription devices are specifically designed to focus on and record transcriptions of a conversation, discussion or interview between two or more people.
Digital transcription equipment, on the other hand, while not directly intended to deliberately do so, has the ability to block out all external noise allowing the user of the device to remain focused on the recording of excerpts or full notes of conversations, discussions or interviews in particularly noisy environments. It remains a standard tool of use for professional journalists and writers who need to make recordings, not so much to do with obtaining accurate interpretations of what the interview revealed but also for the purpose of keeping records, and not just for posterity but for more important professional reasons.
Interviews always need to be arranged at the convenience of the person being interviewed. Some people are reluctant to be interviewed due to the nature of the material being discussed, sensitive, controversial, objectionable or otherwise. The very fact that they have agreed to be interviewed is always welcome to the professional. So, he or she is only too happy to accede to an environment that is as comfortable for his or subject as possible.
So, if a noisy, busy mall has been selected, then so be it. But no matter, the digital technology is able to block out the surrounding noise. Also, the device is small enough to be stationed discreetly and without imposing on the person being interviewed.
