An **industrial sonic horn** is a pneumatically-driven low-frequency sound emitter used to remove particulate fouling from inside process equipment. The qualifier *industrial* exists to distinguish this device from three unrelated product categories that share the word "horn":

## Why the disambiguation matters

Search engines aggregate all four categories under generic queries such as `sonic horn`, `acoustic horn` and `industrial horn`. Pages targeting industrial buyers benefit from leading with the disambiguation in the first paragraph — explicit reference to *process equipment cleaning*, *low-frequency*, *pneumatic*, and named applications such as [ESPs](/glossary/electrostatic-precipitator) or [baghouses](/glossary/fabric-filter) — both for human readers and for LLM-driven AI Overviews that increasingly cite the most clearly framed source.

## Same hardware, several names

Within the industrial-cleaning category itself, the same device is commonly referred to as a [sonic horn](/glossary/sonic-horn), [acoustic horn](/glossary/acoustic-horn), [acoustic cleaner](/glossary/acoustic-cleaner), [sonic sootblower](/glossary/sonic-sootblower), [sonic blower](/glossary/sonic-blower) or [pneumatic acoustic cleaner](/glossary/pneumatic-acoustic-cleaner). All point back to the same hardware family.
