My parent cannot hear phone calls clearly: what can help?

NIDCD says hearing loss that appears all at once or over a few days can be a medical emergency. Seek medical care immediately, even if you suspect wax, congestion or an equipment problem. Delaying assessment can reduce treatment effectiveness. NIDCD: sudden deafness.

This article cannot distinguish the cause. The suggestions below are for ongoing communication difficulties, not a reason to postpone urgent assessment.

NIDCD recommends facing the person, speaking clearly without shouting and reducing background noise. A video call may make facial cues available if the person wants that format. Persistent hearing concerns can be discussed with a primary-care clinician, audiologist or ear, nose and throat specialist. NIDCD: hearing loss and family communication.

Ask which part is hard: hearing that the phone is ringing, answering it, hearing speech or understanding a conversation with several people. These are different problems. Do not assume every missed call means they did not hear it.

What if the ring is the problem?

Ringtone volume alerts someone to an incoming call; call volume changes the voice heard after answering. A flashing or vibrating alert may help with a missed ring. Test it where your parent normally keeps the phone. Raising the ringer does not make the caller's speech clearer. NIDCD: listening and alerting devices.

Write down the exact phone model, software version and hearing-aid model. Check both manufacturers' guidance for the connection you want: listening near the handset, using a telecoil, or streaming calls wirelessly. A hearing-aid compatibility label alone does not establish Bluetooth streaming or hands-free speaking.

For iPhone, use Apple's hearing-device list and system requirements; for Android, start with Google's hearing-device guidance and the phone maker. Ask which microphone picks up your voice. Older M/T ratings describe microphone and telecoil modes; newer testing uses a different format. M4/T4 is not a universal requirement or performance guarantee. FDA compatibility guidance.

Our suggested trial is one short call in a quieter room. Change only one thing at a time, such as the sound output or a caption setting, and ask whether it is easier. Keep volume comfortable; turning it to maximum is not the objective.

With your parent's agreement, try this checklist on a low-stakes call with someone they know. For each step, note: worked, needed help, did not work, or not tried.

1. Notice and answer: Leave the phone in its usual place. Can your parent notice the chosen ring, light or vibration and answer without rushing?
2. Follow the conversation: Use a comfortable volume. Ask whether the words are easier to follow with the one change you are trying.
3. Be heard: Confirm the caller can hear your parent's reply with the intended hearing-aid, handset or speaker setup.
4. Use controls: Find the volume, mute and end-call controls. Can your parent use them without help if they want to?
5. Read captions, if supported: Check text size and whether captions cover controls. Try a made-up name and appointment time, then clarify any mismatch with the speaker.
6. End and reconnect: End the call and call back. After the usual hearing-aid charging routine, check reconnection and where call audio plays.
7. Repeat and decide: If comfortable, repeat with the helper no longer beside your parent. Note what helped, what failed and who will help next. Review before any return deadline.

Write down an accessible fallback and who can help if connection, captions or power fail. Do not call 911 as a test or disconnect essential equipment to simulate an outage.

These questions evaluate usability, not hearing ability. Do not use the trial to diagnose hearing loss.

They may be useful tools, but compatibility and suitability vary. Ask a hearing-care professional about the specific difficulty and any hearing-aid connection needs. For a medical video appointment, ask the clinic about captions or other communication support ahead of time. HHS accessibility guidance.

Do not assume an automatically generated transcript is exact. For an important instruction, ask the speaker to clarify and provide a written summary. Confirm names, dates and amounts rather than relying on a potentially misheard word.

Which phone settings should we check?

Confirm the model, installed software, language, region and calling app. Captions for a video do not prove that call captions work.

• iPhone: Apple's iOS 26 guide lists Live Captions for iPhone 11 or later, with language and region limits. Look in Settings, Accessibility, Live Captions. Review text size and call-caption retention options together. Follow the guide for the installed iOS version. Apple cautions against relying on Live Captions in high-risk or emergency situations. Apple's Live Captions guide.
• Android: Google supports call captions on Pixel and selected Android phones; features and languages vary. Search Settings for Live Caption and check call captioning. Some calling apps are unsupported, it is not intended for calls with more than one other person, and Battery Saver turns it off. First setup needs Wi-Fi for a language download. Google's Live Caption guide.

Try an ordinary call in the actual app with the intended hearing-aid connection. Check that the caller can hear your parent and that captions remain usable. Tell the other person when captions are on.

Check the exact model and service. CapTel lists the 840PLUS for a traditional analog telephone line without home internet, but it still needs electrical power. Its internet-only service needs both internet and electricity; losing either prevents calls. A corded handset or wall socket is not proof the whole setup works during an outage. CapTel model requirements; internet-only limitations.

Before changing service, confirm eligibility, household phone/internet charges, and the model's emergency-calling instructions. Keep any required 911 address current and agree on a backup your parent can use. Do not cancel the familiar service until the replacement has been checked. CapTel's emergency-call guidance.

Bring examples of situations that are difficult: ordinary phone calls, groups, television, quiet conversation or hearing alerts. Note whether the change was sudden or gradual, whether one or both ears seem affected, and any other symptoms. Let the professional determine the assessment and options.

Before buying equipment, ask about a demonstration, return terms, setup support and how it works with what your parent already uses. Also review the separate smoke-alarm plan: improving a call does not establish that nighttime warnings will be heard.
