Like countless others globally, Brian Scholl, a psychologist and cognitive scientist at Yale University, found himself frequently using Zoom during the COVID pandemic. In one virtual faculty meeting, Scholl noticed an unusual reaction within himself towards two of his colleagues. Typically, he aligned well with one colleague, but on this occasion, he found himself agreeing more with another colleague, whom he usually disagreed with. Scholl recalls, “Everything he said was so rich and resonant.”
Upon reflecting on the experience, Scholl identified a critical difference in how each colleague presented themselves: the colleague he usually agreed with was using a low-quality microphone on an outdated laptop, while the one he usually disagreed with was speaking from a professional-grade home-recording studio. Scholl began to suspect that the sound quality, rather than the content of their arguments, influenced his opinions.
Recent findings published in the Proceedings of the National Academy of Sciences USA support Scholl’s intuition. Through various experiments, Scholl and his team discovered that poor audio quality led to negative judgments of speakers across different scenarios, despite the content being identical.

Scholl explains, “When using Zoom, we’re all conscious of our appearance but often overlook how we sound to others.” He adds that audio quality can significantly affect perceptions of a person’s intelligence, credibility, and even their attractiveness as a potential date or job candidate.
Our brains are wired to make snap judgments based not just on what people say but also on how they sound. Numerous studies have shown that a person’s confidence level or accent can influence how they are perceived. Scholl wanted to explore if technological distortions would have a similar impact.
To investigate this, Scholl, along with Yale graduate students Robert Walter-Terrill and Joan Danielle Ongchoco, created audio recordings where voices—both human and computer-generated—read scripts on various topics. These topics included a job application, a dating scenario, and a car accident description. While some recordings were crystal clear, others were intentionally distorted to sound tinny, mimicking common issues encountered in digital communications.
The team gathered over 5,100 online participants who listened to one of the recordings and then rated the speaker on various attributes. To ensure participants comprehended the recordings, some were asked to transcribe what they heard.
Regardless of the script or voice type, the tinny audio consistently led to lower ratings in terms of hireability, dateability, credibility, and intelligence. Scholl notes, “This shows the profound influence of perception and how it can lead us to make irrational decisions. Despite knowing that audio quality doesn’t reflect the person’s qualities, our perceptions often operate independently from our rational thoughts.”
Nadine Lavan, a psychologist at Queen Mary University of London not involved in the study, remarked that while the results were anticipated based on prior research, they remain significant and intriguing. She points out that the impact of microphone quality in real-world settings, such as job interviews where responses are more spontaneous, might differ from the study’s controlled environment.
Scholl emphasizes the practical implications: “It’s crucial to understand how you sound to others in online settings. If the quality is poor, taking steps to improve it is important.” He mentions that the colleague with the initially poor sound quality eventually upgraded his microphone, which likely improved others’ perceptions during virtual interactions.
