ARM has published a new report exploring the growing strategic importance of sonic branding and how brands are increasingly using sound not simply as a creative asset, but as a way to connect fragmented media experiences into one consistent brand memory system. At a time when audiences consume media across multiple devices, platforms and environments throughout the day, the report argues that sound is becoming one of the most effective ways for brands to build recognition, emotional connection and long-term memory.
For decades, brands have invested heavily in visual identity systems through logos, colours, typography and design frameworks. However, the report suggests that many brands have yet to fully develop a distinctive audio identity, despite the rapid growth of audio consumption across radio, podcasts, streaming platforms, smart speakers, connected cars and social video.
Sonic branding, sometimes referred to as audio branding, is the strategic use of sound to represent a brand consistently across different consumer touchpoints. This can include sonic logos, mnemonics, music, voice styles, audio cues, app sounds and brand narration. The report highlights that effective sonic branding goes far beyond creating a memorable jingle. Instead, it is about developing a coherent auditory identity that reflects a brand’s personality and values while helping audiences instantly recognise and emotionally connect with the brand.
One of the central themes in the report is the unique emotional power of sound. Audio has the ability to reach audiences quickly and personally, often creating emotional responses before visual processing or conscious thought occurs. Neuroscience research referenced in the report suggests that sound is processed rapidly by the brain and has a particularly strong relationship with memory and emotional recall. As a result, consistent sonic cues can become powerful cognitive shortcuts that help audiences recognise brands almost instantly.
The report points to several globally recognised examples of successful sonic branding, including Netflix’s “ta-dum”, Mastercard’s payment sound and the familiar notification sounds used by technology platforms and mobile applications. These audio cues have become deeply associated with their respective brands, often triggering immediate recognition even in the absence of visual branding.
However, the report argues that sonic branding is becoming increasingly important not simply because of recognition, but because of the fragmented nature of modern media consumption. Consumers no longer engage with brands through one dominant channel. Instead, they move constantly between TV, streaming services, podcasts, social media, connected TV, creator content, retail environments and mobile platforms. Media campaigns are often planned, bought and measured independently across these channels, leading to what the report describes as “visibility without continuity”.
The challenge for marketers is that consumers do not experience brands in channels — they experience them in moments. As attention becomes more fragmented, creating consistent memory structures across those moments becomes increasingly difficult. The report suggests that this is where sonic branding can play a unique role.
Unlike visual assets, sound travels fluidly across devices and environments. Consumers listen while driving, commuting, exercising, cooking, shopping, walking or multitasking. Audio accompanies audiences during moments where visual media may not have the same impact or accessibility. Because of this, consistent sonic branding can create continuity across otherwise disconnected consumer experiences.
For example, a sonic cue heard in a podcast advertisement during a morning commute may later reinforce recognition when the same consumer encounters a social video, connected TV campaign or streaming advertisement later in the day. Rather than processing every exposure as a completely new message, audiences begin to build cumulative memory structures around familiar sounds and voices.
The report argues that the smartest marketers are no longer treating audio advertising as a standalone media channel. Instead, they are increasingly viewing sonic branding as a strategic integration tool that strengthens the effectiveness of the wider media mix.
The distinction the report makes is important: audio media is the distribution channel, while sonic branding is the strategic asset. Podcasts, streaming services, radio, creator reads and social audio provide the platforms for distribution, but it is the consistency of the sonic identity that creates the lasting memory effect.
The report also explores how brands can begin developing an effective sonic identity. The starting point is understanding brand personality and translating that personality into sound. A healthcare or financial services brand may seek calm, reassuring and trustworthy tones, while a technology or gaming brand may lean toward sharper digital textures, modern beats and more futuristic sound design. Travel and lifestyle brands may incorporate natural sounds, movement and atmosphere to evoke emotional associations.
Importantly, the report stresses that the objective should not be to chase audio trends or create novelty. The most effective sonic identities are often simple, emotionally resonant and consistently applied over time. Just as visual logos build recognition through repetition, sonic identities become more valuable the more consistently they are used across platforms and campaigns.
The report highlights that sonic branding can extend across numerous brand touchpoints including broadcast radio, podcasts, streaming audio, social media videos, creator partnerships, in-store experiences, connected devices, apps, customer service environments and even phone hold music. Every audio interaction presents an opportunity to reinforce brand familiarity and emotional connection.
Research referenced throughout the report suggests that sonic branding can deliver measurable commercial impact. Studies cited indicate that sonic branding can improve advertising recall, strengthen purchase intent and increase overall brand power. Additional research highlighted in the report suggests that combining audio with TV, podcasts, connected TV and social campaigns can significantly improve aided recall and message association compared with standalone campaigns.
The report also explores the relationship between audio and search behaviour. Search is often viewed as a demand-capture channel, but branded search activity only occurs when consumers remember a brand in the first place. Sonic branding can help seed future brand recall by creating memorable audio associations that remain accessible during later moments of consideration or purchase intent.
Similarly, the report suggests that creator-led and social content environments are becoming increasingly audio-driven. Voices, recurring phrases, conversational styles and familiar sonic cues travel naturally across podcasts, TikTok, YouTube Shorts, Instagram Reels and livestreams. Brands that maintain consistent sonic identities across these environments are more likely to build familiarity and recognition over time, even as visual executions vary by platform.
Ultimately, the report concludes that sonic branding is evolving from a creative enhancement into a core strategic infrastructure for modern marketing. In an increasingly fragmented media environment, brands that invest in distinctive and consistent audio identities are likely to be better positioned to build recognition, emotional connection and long-term memory with audiences.
As audio consumption continues to grow across radio, podcasts, streaming and connected devices, the report suggests that sound may become one of the most important brand assets marketers have available — not simply because audiences hear it, but because they remember it.
