OBJECTIVE
To investigate the feasibility of using a digital language processor (DLP) to objectively quantify the auditory and social environment of older adults.
DESIGN
Thirty-seven participants aged 64 to 91 years residing in a retirement community were asked to wear a DLP to record their auditory and language environment during 1 waking day. Recordings were analyzed with specialized software to derive quantitative estimates such as the number of spoken words heard and percentage of time spent around meaningful speech versus television/radio.
RESULTS
Adequate DLP recordings that began before 10 AM and lasted for 10 hours or greater were collected from 24 participants. The mean duration of recording was 13 hours and 13 minutes, and individuals spent a mean of 26.7% (range, 4%-58%) of their waking day near a television or other electronic sounds. The projected mean word count over a maximum of 16 hours was 33,141 with nearly a 14-fold range between the lowest and highest observed values (range, 5120-77,882).
CONCLUSIONS
High-quality objective data on the auditory environment of older adults can be feasibly measured with the DLP. Findings from this study may guide future studies investigating auditory and language outcomes in older adults.

PURPOSE
Objective measures of physical functioning and mobility are considered to be the strongest indicators of overall health and mortality risk in older adults. These measures are not routinely used in otolaryngology research. We investigated the feasibility of using a validated physical performance battery to assess the functioning of older adults seen in a tertiary care otolaryngology clinic.
MATERIALS AND METHODS
The Short Physical Performance Battery was performed on 22 individuals aged 50 years or older enrolled in the Studying Multiple Outcomes after Aural Rehabilitative Treatment (SMART) study at Johns Hopkins.
RESULTS
We successfully administered the SPPB to 22 participants, and this testing resulted in minimal participant and provider burden with respect to time, training, and space requirements. The mean time to complete 5 chair stands was 13.0 ± 3.8 seconds. The mean times for the side-by-side, semi-tandem, and tandem stands were 10.0 ± 0.0, 9.5 ± 2.1, and 8.8 ± 3.2 seconds, respectively. Mean walking speed was 1.1 ± 0.3 meters per second, and composite SPPB scores ranged from 6 to 12 (mean = 10.45, S.D. = 1.6).
CONCLUSIONS
Our results demonstrate the feasibility of implementing a standardized physical performance battery to assess physical functioning in a cohort of older adults seen in a tertiary otolaryngology clinic. We provide detailed instructions, references, and analytic methods for implementing the SPPB in future otolaryngology studies involving older adults.
