Door bells, wake-up and fire alarms
To neglect to have fitted a fire alarm which is appropriate for your hearing loss is highly mistaken.
Fire alarms save lives. If you are very hard of hearing it is wise to have an alarm which wakes you at night by vibrating.
There are door bells which are connected to a vibrating signal which one wears.
These are readily available from Action on Hearing Loss (www.actiononhearingloss.org.uk/shop/alerting.aspx). They should be tested out before accepting the purchase.
