New study from Omnicom Media Intelligence and iHeartMedia outlines how evolving audio formats deliver measurable full-funnel impact
The study - Turning Volume into Value: What New Audio Innovations Mean for Advertisers - is based on a controlled experimental design among more than 3,500
With audio now accounting for roughly one-third of daily media consumption, the findings underscore its growing importance within the media mix and its ability to amplify performance across channels.
“Audio is one of the few channels that delivers both scale and intimacy,” said Lainie Fertick, President, iHeartMedia Insights. “When brands combine trusted human voices with thoughtful innovation, audio becomes a powerful driver of trust, engagement and accelerated purchase behavior.”
Audio delivers full-funnel impact - and amplifies other channels
Across formats, audio advertising drove significant lifts in core brand metrics, including a 22-point increase in unaided ad recall among in-market consumers, alongside gains in favorability (+5 points), search intent (+6 points), and purchase intent (+5 points). The research also highlights audio’s “multiplier effect,” demonstrating that exposure to audio ads improves responsiveness across social and digital channels, increasing engagement and branded search activity.
Trusted voices and long-form storytelling enhance credibility and accelerate conversion
Host-read ads emerged as particularly effective in building emotional connection and brand trust. Messages delivered by familiar or trusted voices generated stronger gains in brand relevance, search intent, and purchase intent than standard ads, reinforcing the influence of the listener-host relationship.
The study also found that trusted hosts accelerate decision-making. Exposure to host-read ads drove a 20-point lift in likelihood to purchase within a week, significantly outperforming standard ads.
Long-form host-read executions further amplified these effects. By allowing more time for storytelling, these formats delivered up to 2X higher recall than shorter ads and increased the likelihood of near-term purchase, making them especially effective for consideration and conversion objectives.
“Listeners develop real relationships with the voices they hear every day,” said Kara Manatt, EVP, Intelligence Solutions, Omnicom Media. “When brands tap into that credibility at scale, the impact is measurable - trusted voices don’t just influence perception, they drive action.”
Innovation in creative formats boosts relevance, engagement and action
Emerging formats are also expanding what audio can do for brands. Dynamic ads tailored to context - such as time of day or listener environment - improved perceived relevance (
Interactive motion-activated units, which prompt listeners to engage directly, proved especially effective among younger and in-market audiences, generating incremental gains in both search and purchase intent. These formats transform passive listening into active participation, helping brands convert high-intent consumers more efficiently.
Beyond individual tactics, the study emphasizes the importance of sequencing formats strategically. Combining trusted host-read ads with dynamic and interactive elements enables brands to guide consumers from awareness through to action within a cohesive audio strategy.
