Lucas and Luna investigate how smartphone microphones can be used to trigger targeted ads even when apps appear idle. They examine a 2025 study by researchers at Northeastern University that found 23 popular Android apps sending audio metadata to ad networks without explicit user consent. The hosts break down the technical mechanism called 'ultrasonic cross-device tracking' where inaudible beacons embedded in TV ads or store audio are picked up by phone mics, triggering targeted ads minutes later. They discuss the FTC's current investigation into three major ad-tech firms, the limitations of GDPR and CCPA in addressing this practice, and practical steps listeners can take today to limit exposure. The episode concludes with a reflection on how privacy regulations are struggling to keep pace with surveillance technology. #SmartphonePrivacy #UltrasonicTracking #TargetedAds #MicrophoneSurveillance #AdTech #FTC #GDPR #CCPA #NortheasternUniversity #PrivacyStudy #AndroidPrivacy #DataBrokers #CrossDeviceTracking #AudioBeacon #DigitalPrivacy #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
