An elevator controller provided to an elevator capable of lessening the unpleasant feeling of the passenger(s) due to ear popping without lowering the operation efficiency of the elevator more than required. An elevation / descent distance calculating section (13) calculates the elevation / descent distance of the car (1) controlled by the elevator controller from destination floor information (12a) and car position command signal (3a) and outputs elevation / descent distance information (13a) to a speed pattern generating section (14). The speed pattern generating section (14) compares in magnitude the elevation / descent distance and a predetermined distance. If the elevation / descent distance is shorter than the predetermined one, the speed pattern generating section (14) generates a speed pattern (14a) for normal operation; if longer, the speed pattern generating section (14) generates a speed pattern (14a) for partial low-speed operation. The predetermined distance indicates the height difference corresponding to the air pressure difference which brings the passenger(s) opening the Eustachian tube to solve the ear popping. A speed control circuit (24) elevates / descends the car (1) according to the speed pattern (14a). As a result, after the first opening of the Eustachian tube, the car (1) elevates / descends at low speed, the interval until the car (1) elevates / descends a height difference causing the next ear popping can be lengthened, and the unpleasant feeling of the passenger(s) due to the ear popping can be lessened.

A device for obtaining an equalization of a negative pressure in the middle ear is disclosed. The device comprises a facemask, an air pump and an air reservoir, all of them connected to a connecting tube. An increased air pressure is created by expiration into the facemask and / or by activating the air pump. A sufficient rise in air pressure in the device makes the air reservoir to expand, and this creates an increased pressure in the mouth / nose cavity and opens the Eustachian tube and forces air into the middle ear for equalization of the negative pressure in the middle ear.
