EarLog is a real‑time, embedded system that opportunistically uses headphone playback as a probe to detect the acoustic reflex (AR), an involuntary ear response indicating protective activation during high‑load listening. By employing content‑conditioned residual sensing, a resonance‑constrained sparse FIR model, and dual‑microphone observations, EarLog suppresses noise from nonstationary content, individual ear acoustics, and device variations to identify weak AR signals. In a study with 81 participants, 16 headphone models, and over 400 hours of recordings, EarLog achieved 99.0% sensitivity and 98.7% specificity against a clinically referenced benchmark, enabling continuous, listener‑specific AR monitoring during everyday listening.

The paper introduces a simulation-based method for detecting a user's own voice in hearing aids using only a single microphone. It employs a data augmentation strategy with simulated acoustic transfer functions to train a transformer classifier, achieving over 90% accuracy on both simulated and real-world recordings. The approach reduces hardware complexity and power consumption while maintaining robust performance across varied spatial conditions.

VM-ARRAYDPS introduces virtual microphones with higher signal‑to‑noise ratios to augment a limited physical microphone array, providing additional multi‑channel consistency constraints for blind speech separation. By leveraging a pretrained speech diffusion model and posterior sampling, the method improves upon the existing ArrayDPS approach. Experiments on 2‑speaker and 3‑speaker datasets show significant performance gains, and ablation studies reveal the impact of virtual microphone count and consistency weighting.

The paper introduces RALCT, a lightweight Convolutional Transformer that combines randomized audio augmentations, MFCCs, and log‑mel spectrograms to extract robust features for environmental sound recognition. With only about 310,000 parameters, RALCT achieves state‑of‑the‑art accuracy—over 93% on UrbanSound8K, peaking at 94.56%—making it suitable for deployment on mobile devices. The authors also develop a mobile app that integrates the model to provide real‑time safety alerts for hearing‑impaired users.

arXiv:2606. 04103v1 Announce Type: cross Abstract: Conventional hearing aids rely on fixed, frequency-dependent amplification and compression to manage reduced sensitivity, which often fails to provide sufficient listening support in complex environments, such as situations with multiple speakers (the ``cocktail party'' problem).
