In the digital domain, what differentiates one hearing instrument from another isn’t its appearance or circuitry; rather, it’s the capabilities of its software algorithms. Maximizing the flexibility of Starkey’s exclusive Genesis hardware platform, Precision Audio Imaging incorporates the essentials of high fidelity, while adding several clinically proven, intelligent signal-processing solutions. Starkey’s Precision Directional Imaging (PDI) products are part of a new series of directional hearing instruments introduced in 2004. PDI products incorporate a new mono-microphone directional design for custom instruments. Advantages of Starkey PDI hearing instruments include: • Highest directivity available • Available in Full Shell through ITC models • Elimination of microphone drift • Better sound quality • Low noise performance • Long battery life
