The speaker feels heavy-hearted and separated from daily life.
Explanation:
Sir Alfred Lord Tennyson's poem "In Memoriam" is written as a requiem for his close friend Arthur Henry Hallam. Arthur died of a sudden case of cerebral hemorrhage in 1833, leaving Tennyson devastated and alone.
This poem talks of how the 'light' of his friend had left his presence, alienating the poet. The lines given in the question are from the last stanza of the poem where he expressed his grief at the death of his friend. Hinting that there is life after death, the poet says "<em>the noise of life begins again</em>". Through this stanza, we can see that Arthur's death left the poet feeling dejected, heavy hearted and alienated from the normal daily life routines.
