All our testing equiptment is calibrated specifically for mobile operations and we only use the best on the market.
When hearing thresholds are measured during home-visit hearing tests, we use a special type of ear plug called "inserts" which allow for greater sound attentionation in comparsiion to over-the-ear headphones often used in clinics. This allows for accurate testing even with background sounds present. Furthermore, ambient noise-floor levels are always live-measured during testing, to ensure all results are accurate and adhering to industry standards.
That being said, clearly, all testing of hearing must be performed without signifcant background noise present at homes. Examples of noises not tolerated during testing includes families talking loudly in a room next door or children running around the house.
Generally speaking, the only times testing would not be appropriate to perform at someone's home would be if the house was directly on a very busy road, or road works were being performed outside. If this is the case, please let us know prior to booking your appointment.
